Figure 4.

Time of thermal stimulation response(s). There was no difference in time of thermal stimulation response in three groups at 7 days. PMSC treatment significantly improved thermal stimulus response at 14 and 28 days compared with the control group. LGK974 inhibitor significantly decreased the therapeutic effect of PMSCs. ^∗PMSC group vs. the control group, P < 0.05; ^#PMSC group vs. PMSC+LGK974 group, P < 0.05 (a). No significant difference between control group and LGK974 group at 7, 14, and 28 days (b).
