Figure 2From: Sodium-calcium exchanger and multiple sodium channel isoforms in intra-epidermal nerve terminals NCX expression in free nerve endings within epidermis. PGP 9.5-positive free nerve endings exhibit NCX2, but not NCX1 and NCX3 immunolabelling. NCX2 labeling extends from the dermal boundary to the tip of the nerve terminal. NCX: red; PGP 9.5: green; merge: yellow. Scale bar, 10 μm.Back to article page
