Cord Blood Stem Cells Information

Stem cells? hi, the person who can answer this best can get 10 points. I need to know the difference between these stem cells, potential, how are they extracted, plus they are all different early embryonic stem cells blastocyst embryonic stem cells fetals stem cells umbilical cord stem cells adult stem cells thank you

How are stem cells extracted from their source? I am part of a science project called The Leading Edge Project, and my group's topic is stem cells. We have created a presentation, but we have one nagging question: How are stem cells actually removed from the adult body/other source? We know where they come from and what they are, but we'd really appreciate knowing HOW they are extracted.

What does it mean for stem cells to remain unspecialized or become specialized? I read and article about stem cells and there's this section that I don't really understand. "Therefore, in order to develop such treatments scientists are intensively studying the fundamental properties of stem cells, which include: 1. determining precisely how stem cells remain unspecialized and self renewing for many years; and 2. identifying the signals that cause stem cells to become specialized cells. " So what unspecialized and specialized cells mean? And if you can, can you also explain briefly what stem cells are and capable of? Thank you. :]

What are the main chracteristic differences between stem cells and normal human cells? i know that a stem cell is a non differentiated cell, and can grow into almost any kind of cell. and that there are 3 main types and where they can come from. i need to put this question's answer/s into a context that i could maybe put it into a table comparing stem cells and normal cells. Anything else in relation to your viewpoint on the issue is also appreciated. ~this is for study into a science assignment, any help is appreciated.~ could you maybe tell me also what things stem cells do that normal cells dont and vice versa. What are the organelles in a stem cell, how do they function ... do they have organelles? thanks

How do you refer to embryonic stem cells and reprogrammed skin cells to meiosis and mitosis? The question pretty much says it all. What im trying to ask is: how do i identify the interrelationships of Meiosis and mitosis and the systemic level (ZYGOTE) with respect to stem cells and reprogrammed skin cells? its one of my questions on my assignment and its really confusing me, any help would be much appreciated! :)

What research has been conducted in the field of stem cells for the regrowth of nerve cells? I want to know more about this field but need a basic knowledge. I also want to know about HOW these results were achieved. Has there been any revolutionary scientific breakthroughs either in stem cell research recently. And could anyone please inform me about how far we off maybe regrowing USABLE nerve cells and any key info related to this subject.

What do we really know about stem cells? If someone is given stem cells from a fetus wouldn't they have to take medication to keep from rejecting them? Wouldn't it be more logical to use the stem cells that the body already produces? I wonder how hard it is to harvest stem cells?

What research has been conducted in the field of stem cells and what are the summarised results? I want to know more about this field but need a basic knowledge. I also want to know about HOW these results were achieved. Has there been any revolutionary scientific breakthroughs either in stem cell research. And could anyone please inform me about how far we off maybe curing cancer or regrowing USABLE nerve cells and any key info on either of these subjects. Thanks.

What are stem cells and how can they be used? Can someone please explain to me what they are using simple terms? Everything I read on the internet is so complicated. Where can we get stem cells?

How many retarded people out there think you have to kill babies to get stem cells? I had my daughters stem cells saved when I gave birth. It was the smartest thing I've ever done in my life. She turned out to have heart defects, and needed surgery 5 days after she was born. She will have problems later in life. So now that we have saved her stem cells it can be used to repair her heart. Stem Cells save lives. Someone says it may not happen in my life time. Well, I have faith in them. That's why I donated half to research.

Why use stem cells from a fetus than an adult? I thought that only a fetus had stem cells, but then I found out that everybody has stem cells. Why do they only use stem cells from a fetus when the can use it from fully grown adults? Is there something different from using a fetus stem cells than an adult stem cells?

What chemicals are used to coax stem cells to become a certain kind of cell? I need to know specifics about the chemicals and there compostion that are used to coax stem cells into the cell of choice. Thank you

How do Paralized people make stem cells? If hematopoietic stem cells are found in the bone marrow which is in the hip.What about those who are disjointed from their from the pelvic region and down. That is they don't have that area? Or what if they are paralyzed in the legs?

What are some internet sites or books that I can use to find good information on stem cells/growth factors? I need the information about stem cells, current research, and growth factors that are used to coax them.

Who was the first person to be cured with stem cells? Ive googled it and cant find any examples of anyone actually receiving stem cells and what the results were. Does anyone know anything about this? I would like to know if this is a real healthcare revolution or just a political platform that preys on the hopes of desperate people. Maybe the research is being done somewhere else and its in a different language? And please provide links.

How do genes have a connection with the research of stem cells? I am doing a persuasive essay that stem cell research should continue. And i'm writing that one of the pros of this research is that scientists will have a better picture and know how to "cure" genetic dieseases. So how does the research of stems cells contributed to this.

Does anyone have any experience with saving placenta blood for the stem cells? We are five weeks from our due date. I wonder if it's worth paying to save the stem cells. I know that there are public banks out there. I'm thinking that you'll never know what advances the future will bring so it may be very smart to save these stem cells.

What are some interesting facts on stem cells and human embryology? I need some interestig facts on stem cells, human embryology and just generally smart stuff about the human body... i need some interesting facts on cells (especially stem cells), human embrology, and the human genome

What kind of scientist works with stem cells? I'm starting college soon and want to work with stem cells when I graduate. What kind of scientist works with stem cells? What would I have to major in? Would I need an advanced degree?

Which of the following is not true of adult stem cells? a. They have been found not only in bone marrow, but also in other tissues, including the adult brain. b. Although more difficult to grow than embryonic stem cells, they have been successfully grown in culture and made to differentiate into specialized cells. c. They are differentiated cells that can be induced to dedifferentiate and become totipotent. d. If pluripotent, they are capable of developing into different types of cells under appropriate conditions. e. These relatively unspecialized cells continually reproduce themselves.

Dedifferentiation of adult cells into Embryonic stem cell? To be honest my professor is Korean researcher in US has created the differentiate an adult cell into Embryonic stem cell, using mouse. He did it but, it seems that another researcher stolen or did smth wrong, anyway what ever it was, finally the creator became not him but that person. So I think he wants us to find negative sides of this work (differentiation of adult cells into Ebryonic cell). So please give me more exact negative fact for that. Hope this additiona information wil help you.

Any ideas on how to find a good research mock proposal topic, probably in stem cells/development? It can't be related to my dissertation work so I can't use topics I already know a lot about! That's the biggest problem. So I need to come up with a brand new idea from something I'm not working on. It needs to be in the general area of embryonic stem cells and/or development. At first I was thinking cardiovascular type development but I think I could even expand to different areas of development/differentiation. Usually I come up with my next "line" of research based on what actual research I'm doing, but this must be unrelated. I'm just trying to become an "expert" in every possible field now so I know where the good areas to explore are but that's like trying to do 100 PhDs at once! I have been reading like crazy but I could sure use some more expert advice. If anyone has any good avenues to explore or papers/groups to watch let me know. Any ideas or suggestions? ...How to approach? Thanks.

How is the stem cells treatment in thailand compared to Beike corporation done in China considering the cost? We are trying to get Stem Cell treatment for our 8 yr old son who has CP and severe MR. The treatment in China is expensive. Are there any hospitals in Thailand or anywhere else where it is less expensive but on International standards.

What is the significants of embryonic stem cell research over adult stem cells research? I have been told that there is more potential in saving lives with adult (or other non-embryonic) stem cell research over embryonic stem cell research. I know about the whole genetic arguement (because getting ACS has the genetic code of the patient, the patient will accept it idea) so I know the advantages of ADC over ESC. What are the advantages of ESC over ASC?

What do you think of my Haikus on Stem Cells? my biology teacher set us the homework of righting a poem about stem cells, i chose to do a haiku. WHat do you think of them, whcih is the best and can you make any suggestions. As i watch Stem Cells, From an unborn embryo, imorality. As i watch stem cells, fast becoming specialized, I think is it right.

What do you think about parents who have another child to save the first one, with the stem cells of the new? child? I don't know to much about stem cell research, but couldn't they get stem cells from the parents? And if not, how would you like to know that the only reason you were conceived was so that your sibling could be saved, not necessarily because they wanted you.

Do all tissues contain stem cells? (This is a somewhat leading question, intended to get you to the following? Do all tissues contain stem cells? (This is a somewhat leading question, intended to get you to the following question.) Why is it important that a tissue might have resident stem cells?

Realistically, how long before science will be able to generate organs using our own DNA and stem cells? I'd just read about an experiment where stem cells were grafted onto the "shell" of a rat's heart, and scientists using that as a framework were able to encourage growth such that a living, beating heart arose. How long before this might become available to human beings, any educated guesses if not realistic estimates?

Cancer STEM cells true cause of cancer and researchers missing the ball? What do you think? 1994 Researchers discovered the cancer stem cell in AML (leukemia). Other researchers did not believe it. Since then, about 15 cancers have been found to have cancer stem cells. Now the cancer stem cell is the cell that produces the cancer cell. Treatments for the last 30-40 years target only the cancer cells, missing the stem cell altogether. This may be why you get complete remissions in cancer (no cancer cells), but then the cancer returns because the cancer stem cell remains to regrow the cancer cells. Research is proving this out at Stanford, U Toronto, U Mich. and Hopkins. Yet other research centers and doctors have not picked up on this idea. This is akin to malpractice perhaps. Clinical trials will be coming out to target the cancer stem cells, and if you get some cures, then there will be a complete shift in thinking. Too bad it has taken 40 years.

If it is unknown how long it takes to fully differentiate stem cells, why not just wait a long time? I heard stem cells take a long time to differentiate and that if they don't go completely then their "cures" can be problematic and lead to teratomas so why not just let stem cells rest for a year or something to make sure they are differentiated?

What are the differences between adult and fetal stem cells? Is scientific progress being made that will make it unnecessary to use fetal stem cells or embrionic stem cells?

Why is it OK to clone an animal and kill it for meat, but not OK to use stem cells from an embryo? A little follow on from one of my previous questions. The FDA in the US has approved cloning animals for meat production, but the government won't approve taking stem cells from human embryos which would be destroyed anyway. Presumably they are more concerned about their food. emp, if you think you are "more equal" than a cow, you need more humility. midnight.... read your own link. There is a whole list of research which is not funded.

Who is against Stem cells being used from unborn embryos to save lives? What people are against that? I'm doing a paper on Stem cells. I know that people don't agree with killing unborn embryos but i don't know who really doesn't agree with it. Can anyone help me please!

Is There A Difference Between Embryonic Stem Cells and Those Found In Adults? I read something about how red blood cells or lymphocytes (i am drunk, so i can't quite remember) come from stem cells. If adult humans have stem cells, why can't we use those instead of embryonic stem cells for research (since Bush is a dick about the subject)?

what is exactally embryonic stem cells mean? what can embryonic stem cells do, and is it benificial to human beings.

How many stem cells are found in an adult tissue like cardiac muscle? What is the avarage number of stem cells in adult tissues? Can we find a number like one in one thousand? if they are very low in number, how can they regenerate tissues and compensate dead cells. As I know cells die and old cells are replaced with new cells in many tissues.

Is my understanding of stem cells correct? If they can make a stem cell into a glia cell, they could use them in people who need glia cells. They might be able to do this in the future, but they can't turn stem cells into glia cells yet. Are my above two statements correct? I know this isn't perfect, but I don't understand stem cell research very well, and I need the information for a university science project on schizophrenia. I came across an article that said the brains of schizophrenics have fewer glia cells.

How many people store Cord Blood Stem Cells? We are thinking of storing our expectant childs stem cells from their cord blood. Does anyone know who prevalent this is, I live in Europe but any numbers for America, Australia etc. would help. I have read quite a bit about it but usually from companies in the market so I am looking to see if there is some credibility to this by seeing how many people do it?

Stem cells? OK im reading info on stem cells and it says in this one im reading that there are four types of stem cells. Totipotent,Pluripotent,Multipotent,and Progenitor cells. http://www.stemcellresearchfoundation.org/About/FAQ.htm#1 I have ben reading alot about it and I found many articles with mistakes so I want to know if its the right information. 3 or 4 types of stem cells???

They're already kinda strong for girls so I don't want to make them stronger but I JUST want to make them smarter because frankly they're kinda dumb - is that possible?

Stem cells? How do fertilization clinics happen to have stem cells? Where do they come from? Are they donated by women? How are they used in in-vitro fertilization? Aside from safety concerns for people who receive cell transplants, what reasons do people have against stem cell research?

Stem Cells? Did you hear about the new technology that made skin cells act like any other cell? They are doing the same thing as stem cells but without killing fetuses, they can mimic any cells your body has lost. Pure magic. Sorry, i have no idea how this ended up in religion.. I was being figurative about the word "magic" and "fetuses" if you were too D.U.M. to figure it out...

stem cells? Why do people have to pay so much for stem cells? It comes from our body. If I wanted to draw the blood out from the umbillical cord myself w/ a syringe, and store it in my freezer, Why not? What are our rights when it comes to our baby's stem cells? Does someone have more information on my concerns?

Stem Cells ...? For a presentation, I'd like to know: What are Stem Cells used for? What are the For & Against Arguments for the use of them? And opinions to back up the pros and cons? Thank you! :D

Stem Cells? Not many people know that the "fetuses" used for stem cells are actually the fertilized eggs infertile couples use to have a child, the doctors make dozens of extras to better increase the odds of getting the woman pregnant. The ones they dont use are thrown away like common garbage. (or more like common biohazard garbage.) So my question is if it is murder to use stem cells to potentionally save another life, then why is it that doctors are allowed to make dozens of fertilized eggs and throw away the extras? Its just a freindly debate so please no one get too offended.. I could debate either way and dont have too strong a moral conviction.

Stem cells? Why are you religious nuts against research into stem cells. The possibilities to help people are huge, yet you guys are against it. They are just cells, the cells are alive yes but they are not a person and never will be.

stem cells? Are stem cells extractecd during the blastocyst stage? Is the blastocyst stage considered a embryo?

Stem Cells ? Hi pals, I am a mathematician and a chemist. There's been a lot of hype on Stem cells. Can someone tell me what are they and why is there so much fuzz about them ? -TG http://hotbacteria.blogspot.com

Stem cells...? Hi! What makes a stem cell pluripotent? Is it just the fact that it was taken from an already differentiated cell and it cannot be reversed? Is it not possible for a stem cell to produce, say, an oocyte, so that really, it's totipotent? (Because a fertilized egg is the ultimate totipotent cell) Or am I taking this too far... like, is the difference b/w toti- & pluripotency only *relatively* short term? Thanks!

Stem Cells? I am 28 yr, suffering from Cerebellar Ataxia, (progressive disablities, its very difficult to perform daily activities with such disease) there is no cure for this, but recently stem cell transplantaion is taking place in some countries. If some one have already transplanted stem cell in Cerebellum (part of brain), Is it OK, is the treatment is permanent ?

stem cells?

stem cells? it seems to me the conservative base are the first to judge anyone and everyone that disagree are not cristian or think that science is good for america untill it can be sold to our enemies and challenge corprate greed do you agree

Cancer stem cells are the true cause of cancer? Cancer stem cells were first postulated over 100 years ago. Biologist named Beard called then germ cells that produce cancer cells in 1902-1906 Then in 1994-97 researchers finally did isolate the first cancer stem cell, in leukemia. Since then cancer stem cells have been found in multiple cancers like breast, colon, pancreas, myeloma, and brain. Leading research centers for cancer stem cell work are Johns Hopkins, Stanford, and U Michigan. There are some clinical trials soon to start to target cancer stem cells. So, what is a cancer stem cell? it is the cell that produces the actually cancer cell. Stem cells divide into more stem cells and progenitor cells that go on to be mature cells. So the cancer stem cell will reproduce itself and more cancer cells. Current therapies do not kill the cancer stem cells, so they then can then produce more cancer cells. If you can kills of all cancer stem cells, then the cancer may be cured. T

Why are stem cells good? I'm doing a major college essay, and so far I've only found solid reasons why they are bad, i.e. ethical and moral issues, etc. I need equally strong reasons as to why stem cell research is a positive thing because the paper is Pro and Con-->Basically a persuasive essay supporting stem cells, and another discouraging it combined in one. My professor also asserted that this is one of the biggest grades we could possibly obtain in his class. PLEASE contribute extremely strong reasons as to why stem cell research is positive, and explain them. I need a Works Cited page as well so please provide the source. Thanks a LOT

Stem cells - they can potentialy become various cells, in stem cell research how do we control the process? What Im trying to ask is if an embylogical stem cell can become any type of cell, or an adult (eg- heamopetic stem cell) can diff to WBC, RBC etc- how do scientist use these cells to grow into the cells they want to use for that particular reason? (Another way to put it -as opposed to getting a haemopetic stem cell for example and seeking a a RBC, how do scientist make sure it doesnt become a WBC?) Thanks :)

Embryonic Stem cells vs. Adult Stem cells? Alright, so what advantage do embryonic stem cells have over adult stem cells? Researchers say that embryonic stem cells have so much potential? There must be a reason that we are still researching embryonic stem cells if adult stem cells are already fixing things. Input? And I'd also appreciate it if you took a look at my other question: http://answers.yahoo.com/question/index;_ylt=Aok3t_V_hUZXRzFyYG7XNkjsy6IX;_ylv=3?qid=20080330124721AAG8GYS Thanks in advance!

Stem cells and cloning? •Stems cells can be totipotent, pluripotent or multipotent. What do each of these terms mean? With this in mind, why are pluripotent embryonic stem cells used in therapeutic cloning research? •Give two examples (other than treatment of Parkinson’s disease) of how embryonic stem cells could be used to treat disease. •Why is the use of adult stem cells often unsatisfactory for therapeutic cloning? Give an example where adult stem cells have been used to treat/cure a disease. •Give two realistic/sensible (even if you do not believe in reproductive cloning) uses of reproductive cloning. Justify their use.

Adult Stem Cell and Embryonic Stem Cells.? Okay, can somebody tell me if I am correct? Adult stem cells are cells found in any human being. They can be found in various tissues. When cloning these cells, you can only replicated it to be the same cell. So, if it was a skin cell, it could only turn into another skin cell. Sometimes a body doesn't accept these cloned cells, though. Alright, and then the embryonic cells. they are an embryo that is taken from a mother's womb. They can be used with any sort of tissue, and will be a custom fit with any body. Am I right? If not, somebody please explain the difference. Also, why would somebody use an adult cell over the embryonic cell, and vice versa? How do the embryonic cells fight diseases? your answers are greatly appreciated.

How are the 3 main stem cells Embryonic stem cell Embryonic germ cell Adult stem cell different to body cells? so yeah how are the Embryonic germ cells Embryonic stem cells and adult stem cells different to body cells???? thanks in advance

Can stem cells directly become red blood cells? or for that matter, any kind of blood cells. what are Hematopoietic stem cells in depth. How would a Eukariotic stem cell become a blood cell dirctly? is a blood cell Procariotic? In other ways, i've heard stem cells become cells that create red blood cells? is this in the marrow? please explain!! TY!!

Qns on Stem Cells? I have an upcoming project. Answerer will be given credits. Well the qns here is: 1) What controversy has the stem cell research ignited? 2) What is the difference between an adult stem cell and embryonic stem cells? Thank you.! ;)

What are stem cells and how are they important? Explain for a 10 year old, please.? We are learning about brain traums in class. Our guest speaker from the Hall of Health told us about stem cells being something to help us repair our brains. Our teacher told us afterwards thatthere are two sides to the story. He said that stem cells are very powerful and useful infixing things, but there is controversy about if we should use them because the most powerful come from fetuses. He wouldn't tell us if it was right or wrong because he said that's what we're supposed to figure out. We have to talk with our parents about how stem cells are used and we have to talk about abortions. You know, is it right to use them. Our teacher also told us that the president has a thing right now where we can use stem cells we already have for research but he doesn't want us to keep getting more but states can have opinions. Also our teacher said there are different kinds of stem cells and people are studying how to use animal cells. Very cool. My parents said they dont know,"Go look it up."

Embryonic Stem Cells. Research without complete destruction? Can it be done? Can they harvest stem cells from embryos without completely killing the embryo? If the cells can multiply infinitly, why take them all? I don't believe in killing a developing child for use of its stem cells. Regardless of the fact that they are used for medical purposes and they would be disgarded anyway, I think it is still wrong. They have the highest rate of success, vs. adult stem cells. Those can be found in the ear and in some other places. There aren't many successful alternatives to ESC harvesting. I know I might feel differently if MY child had a condition that could be cured with ESC. I would want the best treatment possible. It's good that they have found stem cells in cord blood, but harvesting/preserving it takes thousands of dollars. We were talking about this today in class and I'm trying to find out more. If you don't think it counts as murder, please explain why. Thanks in advance to all serious answers Kelsey

embryonic stem cells! HELP PLEASE!? hey. how do embryonic stem cells get their nutrition? if you do not know the answer to this can you please tell me how they either perform regulation (control and coordination of their activities) or transport. HELP IS APPRECIATED THANKS

Scientists Use SKIN Cells to create Stem cells, will libs still demand the use of stem cells from abortions? http://news.yahoo.com/s/ap/20070606/ap_on_sc/stem_cells NEW YORK - In a leap forward for stem cell research, three independent teams of scientists reported Wednesday that they have produced the equivalent of embryonic stem cells in mice without the controversial destruction of embryos. They got ordinary skin cells to behave like stem cells. If the same could be done with human cells — a big if — the procedure could lead to breakthrough medical treatments without the contentious ethical and political debates surrounding the use of embryos. Experts were impressed by the achievement. st judy's comet...good answer...i'm only biased against the use of stem cells from aborted children paid for by the guv or TAX payers who then in turn finance billions in research again!!! it's a racket...stem cells yes...aborted children no....but good answer. kudos.

Stem Cells: Is there a preponderance of these from one parent over the other? Where do my stem cells stem from (is one parent favored over the other in terms of the genome it contains)? Or are stem cells composed of both mom and dad's genome? What does "Chimerism" mean in light of stem cells for a male offspring (me).

why lill babies to get stem cell when we could use adult stem cells without sacrificing life? my question is, why do peple want to kill a living being to get the stem cell. adult stem cells do just as much and nobody is killed. im not a republican, but it seems to be a common sense answer. i mean, killing babies to get the stem cell for research is a lot like ripping someones heart out where they stand to see how it pumps. its ridiculous. also, to say something, i admit that cells in a human body r not life, except at conception because its the earliest stage of life. i also admit that it has many uses, but in reality embryonic stem cell research is just murder, and a good alternative is adult stem cell research, which is much more moral. as a note, i normally hate bush, but he was right on this one. i do not want my tax dollars going to the killing of innocent PEOPLE. now if only he could pull our troops back. what do u think on this issue, please be detailed.

Can stem cells lose their efficacy? If humans are getting weaker, due to pollution and other factors, will stem cells begin to lose their effectiveness over generations? Males have already begun to have lowered testosterone levels. Some studies show brain size as shrinking. I wonder if stem cells themselves will eventually be affected, losing their potency. P.S. I am against stem cell reserach, but not because of religious reasons, (i.e. the whole embryonic stem cell debate).

Stem cells from amniotic fluid - will religious stem cell opponents still be opposed? Today scientists announced that they have found useful stem cells in the amniotic fluid of pregnant mothers. This method will completely avoid the religion-based "destruction of the zygot" concern. Will religious opponents of stem cells oppose this method as well? http://news.yahoo.com/s/nm/20070107/sc_nm/stemcells_fluid_dc_1 So Julian, are you opposed to medical science altogether? Why does god allow us to discover ways to treat and prevent disease and suffering? Jim, I'd love to think you are right that christians will all feel this way, but check out Julian's response. We are not trying to be bigots, we are just concerned that fundys such as Julian will continue to prevent the use of useful stem cells.

Germ cells vs. Stem cells? how are the different types of stem cells (adult stem cells and embryonic stem cells) different from germ cells?

Do human stem cells have a right to life? People who say abortion isn't murder, because an embryo isn't a living human may not be aware of the high value scientists place on stem cells. Researchers seem to think they are more important than common tissue, such as skin, bone, or liver cells. Aren't stem cells themselves, the essence of human life in it's smallest form? Unlike common tissue, stem cells have the unique ability to produce any, and all the other types of cells. There seems to be a contradiction here, between the abortionists, and the researchers. The former places little value on minute quantities of human tissue, the latter seems to think very small amounts of some tissue can be the salvation of the human species.

What is a stem cell? Describe the process in which stem cells become differentiated.? The whole question... What is a stem cell? Descridbe the process by which stem cells become differentiated. Gived the current ethical delimmas that surround this type of research, briefly summarize the prons and cons of stem cell usage. What possible alternatives are there to the use of stem cells?

Have we discovered a way for adult stem cells to achieve plasticity or is this still under investigation? One difference between embryonic and adult stem cells is that embryonic stem cells have plasticity or the ability to change into all cell types and tissues in your body whereas adult stem cells can only change into the specific cell from the tissue it was taken from. Scientific articles are saying that adult stem cells can also achieve plasticity, but is this only a theory or has it been scientifically proven? If adult stem cells also contain plasticity, then there seems no point in using embryonic stem cells anymore because adult stem cells would be just as effective and not involve the destruction of embryos.

Sickle Cell cured... but without embryonic stem cells. Is following God maybe right? So we go down this path thinking we have to kill evolving babies to save lives and right here under our noses, we find by forcing avoidance of such thing, we might have came up with a major cure. This is just in... Scientist cured Sickle Cell Anemia in mice. In fact they don't know how they could have done it with embryonic stem cells. They did it with "embryo-like" stem cells from mice tails. http://news.yahoo.com/s/ap/20071206/ap_on_sc/stem_cells_sickle_cell Maybe by following God's wishes we make things better for all instead of preventing good things. Bryan the bible uses the word "murder" as abortion is a nice word thought up by those that wants to fool you into believing it is a medical term instead of what it really is. Just cells and parasites at that, right Bryan? And a fetus is such a great big complicated word, it certainly doesn't mean baby, right? I've been in the medical field too long Bryan, and no longer impressed with medical terms. It wasn't Roe v. Wade that made abortion possible or popular, but a doctor. One that has done more abortions than any other living doctor. See what you think about his medical terms, Bryan. This is the Father of legalized abortion in the USA: http://www.aboutabortions.com/Confess.html And how he and Betty Friedan got it started with NARAL: http://www.pregnantpause.org/abort/remember-naral.htm And how many years have you been in the research world, Corrosion? LOL! I was probably working on monoclonal antibodies before you were born.
