Fig. 3. Expression levels of (a) CD86, (b) CD38, (c) Gpr18, (d) Egr2, and (e) Myc in sciatic nerve stumps at 0 day, 1 day, 4 days, 7 days, and 14 days after nerve injury. The relative expression levels of target genes CD86, CD38, Gpr18, Egr2, and Myc were normalized with reference gene GAPDH. Data were presented as means ± SEM. Asterisks indicated statistically significant differences compared with 0 day control (*, p-value < 0.05; ordinary one-way anova; n = 3).
