Intra-epidermal nerve fiber density (IENFD). a Representative photomicrographs of the histological sections of the footpads of normal and diabetic rats. Intra-epidermal nerve fibers (arrows) were detected by immunohistological staining for PGP9.5. Bar = 10μm. b Quantitative analysis for IENFD of the footpads of normal and diabetic rats. Results are expressed as means ± SEM (n = 4). *P < 0.05, **P < 0.01. DPSC dental pulp stem cell
