Fig 7. Co-localization of KRT20 and neuroendocrine marker synaptophysin (SYP) in grafted ESS.

Fig 7

Immunohistochemistry was performed using antibodies against KRT20 (green) and SYP (red); nuclei were counterstained with DAPI (blue). A-F, Cross sections of ESS at 4 weeks (A), 6 weeks (B), 8 weeks (C), 10 weeks (D), 12 weeks (E), and 14 weeks (F) after grafting; sections are oriented with the epidermis at the top of each image. Arrows indicate examples of KRT20/SYP-positive Merkel cells. G-L, Epidermal sheets of ESS at 4 weeks (G), 6 weeks (H), 8 weeks (I), 10 weeks (J), 12 weeks (K), and 14 weeks (L) after grafting, photographed en face following immunostaining. Scale bar in A is for all images (50 μm).
