ABSTRACT
Objective To investigate the expression of endometrial developing-related genes,the endometrium-like structure and cells during spontaneous differentiation of hESCs. Methods (1) Embryoid bodies were cultured in suspension for 14 days,fixed in 10% neutral-buffered formalin and embedded in paraffin.Estrogen receptor(ER) was detected by immunocytochemical staining.(2) hESCs were cultured in a 35 mm plastic dish and differentiated spontaneously for 10 days.The expression of ER and Vimentin/Keratin was detected by double immunofluorescence histochemistry.(3) hESCs were cultured in a 35 mm plastic dish and differentiated for 5 days.The expressions of endometrial developing-related genes including Wnt4,Wnt7a,Wnt5a,Hoxa10,Hoxa11 and ER were detected by RT-PCR. Results (1) The endometrium-like structures were detected in 14-day-old EBs and some were positive for ER staining.(2) Some spontaneously differentiated cells from hESCs for 10 days were positive for ER together with Vimentin/Keratin.(3)Wnt7a,Wnt4,Hoxa10,Hoxa11 and ER were detected by RT-PCR in hESCs which were differentiated spontaneously for 5 days.Conclusion During the spontaneous differentiation of hESCs,some cells are liable to differentiate into endometrial stem cells and endometrium-like cells.However,further identifications of the whole development process are needed to be done in the future.
