Fig. 6From: Dose-effect relationship and molecular mechanism by which BMSC-derived exosomes promote peripheral nerve regeneration after crush injurySciatic nerve motor functional index (SFI). a Preoperative and postoperative SFI at each time point. b At 28 days after SNC, the SFI in each group was compared and analyzed. Asterisks indicate that the difference between the two groups was statistically significant. Three asterisks indicate p < 0.001, two asterisks indicate p < 0.01, and a single asterisk indicates p < 0.05. Number sign indicates that compared with the PBS group, p < 0.01, the difference was statistically significantBack to article page
