Abstract: Stem cells exhibit unique properties, including the capacity of self?鄄renew and differentiate into all cell types. They consist of embryonic stem cells(ESCs) and adult stem cells(ASCs). ESCs are totipotent cells, which derived from the inner cell mass(ICM) of blastocysts. They have the potential to differentiate into all cell types, including germ cells. In recent years, considerable progress has been made in the study of human ESCs. Human ESCs can differentiate into sperm cells and mature occytes in vitro. However, clinical use of ESCs faces the immunological rejection, oncogenicity and ethical controversies problems. ASC is a kind of pluripotent stem cell, so it can also differentiate into germ cell in certain condition. ASCs can advoid these problems, and they may have a better perpective. If germ cell should be derivered from ASCs in clinical application and produce live offspring. The approach could possibly provide new treatments for infertility. In this reviews, we will induce the progress that ESCs and ASCs differentiate into germ cells.
