Fig. 3From: Effects of low-intensity pulsed ultrasound (LIPUS)-pretreated human amnion-derived mesenchymal stem cell (hAD-MSC) transplantation on primary ovarian insufficiency in ratsIn vivo hAD-MSC tracking. a PKH26-labeled hAD-MSCs showed red fluorescence (100×). b,c The labeling rates of PKH26-labeled hAD-MSCs (b) and their subcultured cells (c) were detected by flow cytometry. d The growth curves of PKH26-labeled and unlabeled hAD-MSCs were measured by CCK-8 assay (n = 6). e–g Transplanted hAD-MSCs were observed at 24 h (e), 4 weeks (f), and 8 weeks (g) after cell transplantation in ovaries (100×).
