Cellular characteristics of BMSCs. a Pipeline of this work. b Cell cycle analysis of BMSCs from passages 6 and 10 of in vitro expansion. c Apoptosis analysis of BMSCs from passages 6 and 10 of in vitro expansion. d Senescence of BMSCs from passages 6 and 10 of in vitro expansion. e Cytokine secretory level of BMSCs from passages 6 and 10 of in vitro expansion with (IR+) or without (IR−) irradiation. Data are represented as the mean ± SEM. Student’s t test was performed to compare P6 and P10 BMSCs with significance set at a P value of less than 0.05. *P < 0.05, **P < 0.01. The same letter (lowercase for P10 and uppercase for P6, respectively) indicates no significant difference among different post-irradiation time (Tukey HSD, P < 0.05)
