Spatial regulation of cell junctions and communication channels in the EET. (A–F) Histological sections of representative EETs showing the expression of desmoglein 1 (Dsg1; A), occludin (B), E-cadherin (C), connexin 43 (Cx 43; D), actin (E), and P-cadherin (F). (G) The spatial expression patterns (red colored cells) are schematically summarized. Arrowheads indicate the wound margin. Broken lines denote dermal–epidermal junction. Bar, 200 µm.
