Mel-ADMSCs therapy preserved the integrity of alpha-microtubule and suppression of cellular expression of CD68 in testis by 72 h after IR procedure. A–E Illustrating the microscopic finding (× 400) of immunohistochemical stain for identification of the expression of alpha-microtubule (α-MT) (spindle shape, gray color). F Analytical result of number of α-MT, * vs. other groups with different symbols (†, ‡, §), p < 0.0001. G–K Illustrating the immunofluorescent (IF) microscopic finding (× 400) for identification of CD68-positively stained cells (green color). L Analytical result of number of CD68+ cells, * vs. other groups with different symbols (†, ‡, §), p < 0.0001. HPF, high-power field. All statistical analyses were performed by one-way ANOVA, followed by Bonferroni multiple comparison post hoc test (n = 6 for each group). Symbols (*, †, ‡, §) indicate significance (at 0.05 level)
