Cell Growth Factor and Estrogen Inducing Menstrual Blood-Derived Stem Cells (MenSC) Differentiate into Endometrial Epithelial Cells

Abstract

Extracted MenSC (Menstrual blood-derived stem cells) from female menstrual blood. Added various exogenous factors in-vitro and simulated the female uterine environment to observe how to make MenSC differentiation into Endometrial epithelial cells by artificial induction. MenSCs were divided into 4 groups: 2.5×10−5 mol/L E group, 1.613 nmol/L EGF group, 2.5×10−5 mol/L E+1.613 nmol/L EGF group, control Group (only MenSCs); the relevant indicators of the experiment includes cell staining and Western Blot to detect CK and VIM protein content; RT-PCR to detect CK-19 mRNA and VIM mRNA. The cell staining results showed that E+EGF group had significant differentiation in 7 days and 14 days. CK-19mRNA of E+EGF group was significantly higher than other groups, and the EGF group expression was obviously higher than that of E group, and VIMmRNA expression is opposite to that. The protein expression had the similar performance. MenSC can differentiate into endometrial epithelial cells after induced by E and EFG; and the co-culture of E and EFG can achieve better differentiation, which proves their work together in MenSC differentiate towards endometrial epithelial cells.
