Embryonic stem cells vsembryonic germ cells?

What's the difference between embryonic stem cells and embryonic germ cells? I'd appreciate any good sources as well. Thanks!

1. Embryonic germ cells (EGC) and embryonic stem cells (ESC) have several similar characteristics. Both cell types replicate for an extended period of time, show no chromosomal abnormalities and express a set of markers regarded as characteristic of pluripotent cells. When the culture conditions are favorable, both EGC and ESC cells can spontaneously differentiate into derivatives of endoderm, mesoderm and ectoderm primary germ layers. On the other hand, EGCs and ESCs differ in origin, tumorogenicity, and robustness in culture. ESCs are derived from the inner cell mass of a 5-day old embryo whereas EGCs are derived from the gonadal ridge of a 5-9 week fetus.
