Figure 3From: Expression of Nav1.7 in DRG neurons extends from peripheral terminals in the skin to central preterminal branches and terminals in the dorsal horn Expression of Nav1.7 in glabrous skin. PGP9.5 (green) intraepidermal nerve fibers (IENF) branch from nerve bundles (arrowheads) at dermis/epidermis boundary (dotted line) and ascend in the epidermis. PGP9.5-positive IENF exhibit Nav1.7 (red) immunolabeling. Inset. Both IENF extending to stratum granulosum (more superficial) and to the stratum spinosum exhibit Nav1.7 labeling.Back to article page
