Fig. 1From: Human amnion mesenchymal stem cells restore spermatogenesis in mice with busulfan-induced testis toxicity by inhibiting apoptosis and oxidative stressHuman amnion mesenchymal stem cells (hAMSCs) restored spermatogenesis and elevated testosterone levels in a busulfan-induced testis toxicity mouse model. a Micrographs of mouse testis sections were obtained by HE staining in three groups 1 week and 4 weeks after hAMSC transplantation. Scale bar = 5 μm. n = 10 for each group. b Testosterone expression was tested by ELISA analysis of the three groups 1 week after hAMSC transplantation. c Testosterone expression was determined by ELISA analysis of the three groups 4 weeks after hAMSC transplantation. The results are presented as the mean ± SD. ***p < 0.001 (compared to the BSF group). n = 10 for each groupBack to article page
