These can be maintained in an undifferentiated state and can differentiate into the three germ layers endoderm, ectoderm, and mesoderm. “Embryonic stem cells are pluripotent cells, so we believe ...

In conclusion, our studies indicate that both male germ line stem cells and the supporting environment can retain full functional capability for long periods of time in the absence of normal ...
