NCX2 expression in dermal nerve bundles and epidermal nerve endings. Small bundles of axons in the dermis subjacent to the epidermis exhibit NCX2 immunolabeling. Virtually all PGP 9.5-positive free nerve endings in the epidermis display NCX2 immunoreactivity. Dashed line indicates the border between epidermis (top) and dermis (bottom). NCX2: red; PGP 9.5: green; merge: yellow. Scale bar, 20 μm.
