Morphological analysis and detection of GSH and SOD levels in the testes of mice treated with different concentrations of hUC-MSCs The mice were treated with PTX or hUC-MSCs, and samples were collected 1 week after the treatment. A: The representative images were stained by HE; B: GSH and SOD levels were detected in testicular homogenate; PTX, Paclitaxel; hUC-MSCs, human umbilical cord mesenchymal stem cells; The data were analyzed by one-way ANOVA; p value less than 0.05 was considered significance; *, p < 0.05; **, p < 0.01; ***, p < 0.001; Each bar represented 20 μm. SP Spermatogonia, PS Pachytene spermatocytes, RS Round spermatids, ES Elongated spermatids, LC leydig cells
