Fig. 5From: Human amnion-derived mesenchymal stem cell (hAD-MSC) transplantation improves ovarian function in rats with premature ovarian insufficiency (POI) at least partly through a paracrine mechanismTracking the differentiation of hAD-MSCs in ovaries. The expression of ZP3 (a × 100 and × 800) and FSHR (b × 100 and × 800) in hAD-MSCs was observed at 8 weeks after hAD-MSC transplantation in ovaries. The yellow arrows indicate transplanted hAD-MSCs.
