Effect of MSC transplantation on apoptosis. Apoptotic cells (sham: 18.7 ± 8.1 cells/mm2; PBS: 295 ± 15 cells/mm2; MSCs: 179.3 ± 25.8 cells/mm2) in the injured cortex at 72 h after TBI were reduced in the MSC treatment group compared with the PBS group (A, B) (n = 6 per group). Number of apoptotic cells is presented as the mean ± SD. Bar = 50 μm. **p < 0.01.
