In vitro Differentiation of Germ Cells from Stem Cells.

Stem cells are unique cell types with the ability of self-renewal and differentiation, which mainly include embryonic stem cells, induced pluripotent stem cells, and adult stem cells. Recently, several research groups have reported that stem cells can differentiate into germ cells under appropriate conditions in vitro. Advances in this field have revealed new perspectives for reproductive and regenerative medicine. Here, we review the progress of in vitro gamete production from stem cells.
