*A significant difference was observed among preoperative baseline values, control, and BMSC group (One-Way ANOVA, ). Significant difference between two variables (Mann-Whitney test, ). In two rats, I and bCMEP waves were found in the BMSC group at 7 days after MCAO. NA: not available; Amp: amplitude; Lat: latency.
