FE promotes ADSC proliferation and maintains their multipotent differentiation capacity. a ADSCs were treated with FE at the indicated concentrations. Cell proliferation was assessed by counting the cell numbers at each passage. b The cell surface marker expression of ADSCs at passage 2 was analysed. c The cell surface marker expression of ADSCs at passage 5 was analysed. d The differentiation capacity of human ADSCs into the adipogenic, osteogenic and chondrogenic lineages was analysed. Differentiation was detected with Oil Red O, von Kossa and Alcian Blue staining. Scale bars = 100 μm
