Figure 5From: Sodium-calcium exchanger and multiple sodium channel isoforms in intra-epidermal nerve terminals Sodium channel expression in nerve bundles within the dermis. The small bundles of fibers within the dermis subjacent to the epidermis exhibit NaV1.6, NaV1.7, NaV1.8 and NaV1.9 immunolabeling. NaV1.1 immunolabeling is not detectable within the small nerve bundles. Sodium channels: red; PGP 9.5: green; merge: yellow. Scale bar, 10 μm.Back to article page
