Variable rejection patterns of cultured keratinocyte allografts in the rabbit.
There are many conflicting reports on the survival of cultured keratinocyte allografts (CKAs). Studies were performed in the rabbit model to elucidate further the fate of CKAs. Of 24 CKAs, 7 were identified as technical failures, 13 displayed classical macroscopic evidence of rejection with a prolonged mean survival time of 2.8 days, compared to non-cultured allograft controls (p < 0.01), and 4 failed to display typical macroscopic evidence of rejection. Furthermore, the time to eventual wound healing of the classically rejected CKAs were delayed by 6.0 days (p < 0.0001), compared to identical non-grafted control wounds.
