Fig 5. Expression of growth-associated protein 43 (GAP-43) and tropomyosin receptor kinase A (TrkA).

Quantification by RT- qPCR of GAP-43 (A, B) and TrkA (C, D) mRNA expression in retrieved and in vitro embryonic and adult DRG (n = 4–10). Data represented as mean ± SEM. Two-way ANOVA was performed followed by Tukey’s post-hoc multiple comparison test (* p<0.05; ** p<0.01; *** p<0.001).
