We established a human embryonic stem cell line derived from frozen human embryos of Chinese origin. The cell line expressed the pluripotent markers SSEA-4, TRA-1-60, TRA-1-81, Oct-4, and alkaline phosphatase. The pluripotency of the cell line was also demonstrated in vivo by teratoma formation in severe combined immunodeficiency mice. ⋯ The embryoid bodies were transferred to an adherent culture system in serum-free medium. The differentiating cells derived from the embryoid bodies expressed Nestin and Sox2, markers of neural progenitor cells. After the induction of cyclic AMP for 7 days, the neural progenitor cells had differentiated into neurons and glial cells.
