Fig. 2From: Effects of low-intensity pulsed ultrasound (LIPUS)-pretreated human amnion-derived mesenchymal stem cell (hAD-MSC) transplantation on primary ovarian insufficiency in ratsLIPUS promotes growth factor expression in hAD-MSCs. a The relative mRNA expression levels of FGF2, IGF-1, HGF, and VEGF in hAD-MSCs in the LIPUS and sham irradiation groups were detected by RT-qPCR. b The levels of IGF-1, HGF, and VEGF secreted by hAD-MSCs in the cell supernatant in the LIPUS and sham irradiation groups were detected by ELISA. *P < 0.05, **P < 0.01.
