Fig. 3 — Immunohistochemical analysis of cytokeratins CK5/6, CK7 and CK10 in the epidermis of the four skin types analyzed in this work. The image shows strong CK5/6 immunoreaction (identified in brown) at the basal layer of the epidermis of all samples, whereas suprabasal signal was more evident for PHS and PFS as compared to DHS and DFS. CK7 was negative for all samples, whereas CK10 showed strong positive reaction at suprabasal layers of all samples, with no differences among samples. DHS dorsal hand skin, PHS palmar hand skin, DFS dorsal foot skin, PFS plantar foot skin. Scale bars: 50 µm
