| Research Abstract |
Basic research was performed with inbred rat strain to develope the allogeneic reconstituted skin equivalent inducing local immunotolerance.
Keratinocyte and fibroblast was derived from rat skin, and the keratinocyte was immortalized(AK-E7). The reconstituted skin equivalent, using AK-E7 with fibroblast, showed nearly normal histologic epidermal structure. The cultured supernatant of the fibroblast transfected with IL-10 cDNA(AFB-IL10) inhibited mixed lymphocyte reaction. As the reconstituted skin equivalent using AK-E7 and AFB-IL10 was grafted into autograft model, its partial take was recognized histologically.
