Fig. 3From: Human amniotic mesenchymal stem cells improve ovarian function in natural aging through secreting hepatocyte growth factor and epidermal growth factorHuman amniotic mesenchymal stem cells (hAMSCs) improve the proliferation rate of human granulosa cells (hGCs) and upregulate the expression of hGC markers. a A schematic overview of the hGC filter procedures. b The number of ki67+AMH+ hGCs was evaluated after a co-culture with hAMSCs. c The expression level of the ki67+FSHR+ hGCs was tested after a co-culture with hAMSCs. d The expression level of the ki67+FOXL2+ hGCs was tested after a co-culture with hAMSCs. e The number of ki67+CYP19A1+ hGCs was evaluated after a co-culture with hAMSCs. The experiments were carried out after 7 days of co-culture, n = 3; error bars indicate SD. **p < 0.01, ***p < 0.001, versus the NOA group.
