Identification of cultured male epidermal allografts by detecting Y chromosome DNA fragments in female burn victims

摘要

The existence of cultured male epidermal allografts in 14 bioptic samples of 9 female burned cases was identified by detecting Y chromosome DNA fragments with polymerase chain reaction (PCR). Y chromosome DNA fragments were found in all the samples and the longest case of allograft survival was detected in a 92nd-day sample. This suggests that the survival time of cultured human epidermal allografts on the wounds is longer than those of non-cultured ones.
