Expression of selectin E and P in skin allograft in rats / 第三军医大学学报

ABSTRACT

Objective To study the histocompatibility of tissue engineered skin with the observation of the effects of selectins E and P on the immunological rejection after skin allograft in rats. Methods Tissue engineered skin was prepared as follows The materials obtained from the neonatal SD rats were cultured and then grafted onto the adult Wistar rats. The expression of selectins E and P in the grafted skin was determined with immunohistochemical staining. Results The expression of selectins E and P was significantly higher in the rats with allograft than in the rats with the grafts of tissue-engineered material. Conclusion Selectins E and P play an important role in the immunological rejection after allograft of skin but the tissue-engineered skin graft possesses favorable histocompatibility and shows no obvious immunological rejection.
