Fig. 2From: Observation of viable alloskin vs xenoskin grafted onto subcutaneous tissue wounds after tangential excision in massive burnsH&E (left) and immunochemistry staining (right) for human CK 5/6 of surviving cryopreserved alloskins on day 30 (upper), 50 (middle), and 96 (bottom) post-engraftment. The white dotted line in a shows a band of lymphoid cell infiltration between the recipient’s wound bed and the grafted alloskin. c Arrowheads show the disappearing structures of rete ridges in the epidermis and the joint of the epidermis and dermis becoming smooth. b, d, and f show immunochemistry staining for human CK 5/6; positive expression (arrows) can be observed in the full epidermisBack to article page
