Fig. 3From: Observation of viable alloskin vs xenoskin grafted onto subcutaneous tissue wounds after tangential excision in massive burnsH&E (a, c) and immunochemistry staining (b, d) for human CK 5/6 of surviving fresh pigskins on day 25 (a, b) and 71 (c, d) post-engraftment. The black dotted line shows a sharp dividing line between the pig dermis and the human dermis. c shows the pigskin graft on day 71 post-engraftment; the arrow heads show the rete ridges disappearing in the epidermis, and the arrows show the adipose tissue under the grafted pigskin. b and d show immunochemistry staining for human CK 5/6 with positive expression (arrows) in the full epidermisBack to article page
