Abstract

There is clinical and experimental evidence that skin allografts improve secondary intention wound healing, however the grafts do not take. Because of the special characteristics of the healing process in the fetal period, fetal skin allografts could be presumed to be a good alternative to adult skin allografts, and even to autografts in particular cases. In order to explore the behavior of fetal skin grafts on newborn animals, skin has been grafted to laboratory rabbits of two different ages: 26 fetal skin allografts to fetuses and newborns and 21 neonatal skin allografts to newborns. Macroscopic and microscopic features of the grafted area have been compared at the 7th, 14th and 21st postoperative days. The newborn response to a fetal skin graft was somewhat different from that to a newborn skin allograft, the first showing an earlier increase in graft bed vascularization, less edema and less foreign body reaction.
