Expression of blood group antigens by cultured human epidermal cells.
The presence of blood group antigens on the surface of cultured human epidermal cells has been demonstrated using monoclonal antibody supernatants in indirect immunoperoxidase and immunofluorescence tests. An isoantigen pattern, consistent with the blood group of the donor infant, was detected in cultures derived from 10 different foreskin specimens, and in sections of the epidermis of 5 of these specimens. The A, B, and H antigens were found on the surface of cultured keratinocytes which resembled those of the spinous and granular cell layers of the in vivo epidermis. These antigens were readily detectable throughout the majority of the lifespan of the cells in vitro. This finding may be of relevance to those contemplating allograft transplantation of cultured human epidermis.
