Abstract:
To evaluate the feasibility of using human embryonic fibroblast(HEF) as feeder layer in the culture of human embryonic stem(ES) cells in vitro, we investigated the morphology, the sensitivity to 0.25% trypsin, the growth curve and cell cycle of HEF with DMEM(low glucose) +10% FBS used as culture medium, and then we compared HEF with mouse embryonic fibroblast (MEF). The results showed that both HEF and MEF are adherent cells in vitro, and HEF has longer life span and better growth ability than MEF. In room temperature, HEF is more sensitive to 0.25% trypsin. Our research suggested that HEF can be used as feeder layer in culture of ES cells. HEF has longer service life than MEF and is worthy to be studied further.
