In-vivo MenSC tracking. a GFP-MenSCs efficiently expressed GFP in vitro. b Transplanted cells were observed at 7 days after infusion, and almost all of these cells were located in the ovarian interstitium and not in follicles. Scale bars = 100 μm. c No fluorescent signals in the ovaries at 21 days after cell transplantation. Scale bars = 100 μm. DAPI 4′,6-diamidino-2-phenylindole, GFP green fluorescence protein
