Research Abstract |
We analyzed embryonic stem (ES) cells derived from aging mice model. It was found that some genes of Wnt-beta-Catenin signaling were relatively lower expression compared with control ES cells. Then, we successfully derived ES-like cells from beta-Catenin defected embryos. The ES cells showed severely impaired in pluripotential differentiation under loss of Beta-Catenin, although can maintain self-renewal ability. Additionally, we found mixed germ cell tumor was generated from the beta-Catenin defected cells in vivo. Taken together, beta-Catenin functions pleiotropically in differentiation and tumorigenesis in mouse embryo derived stem cells.
