BMSCs-exosomes affect cell death and inflammation post-TBI. (A) The apoptosis associated proteins Bax and Bcl-2 were analyzed by western blot at 3 days after TBI. β-actin was used as an internal control (n = 4). (B) The mRNA expressions of pro-inflammatory cytokines (IL-1β and TNF-α) were analyzed by real-time PCR and normalized with GAPDH mRNA levels at 1 day after TBI (n = 6). ∗P < 0.05, ∗∗P < 0.01 versus the TBI + PBS group, #P < 0.05, ##P < 0.01 versus the SHAM + PBS group (C).
