abstract：:Embryonic stem cells (ESCs) have the ability to expand indefinitely in vitro and give rise to cells of all three germ layers as well as germ cells. For these reasons, ESCs hold great promise for biomedicine. In order to harness the potential of pluripotent cells, it is necessary to first understand the molecular mecha...
