| Research Abstract |
This study was designed to develop a new artificial skin containing biological active substance acceptable for the treatment of burn injury and chronic skin ulcer. The artificial skin composed of hyaluronic acid spongy containing dibutyryl cyclic AMP was proved very effective in wound healing in animal tests using rats. In addition, the authors focused on the potency of fibroblasts. These cells are able to release vascular endothelial growth factor which is necessary for promoting vasculalization. The artificial skin composed of fibroblasts combined with a two-layered spongy matrix of hyaluronic acid and collagen was proved very effective in wound healing in clinical trials. Through this study, two types of artificial skins were developed. One is an artificial skin containing biological active substance. Another is an artificial skin containing fibroblasts which are able to release biological active substances.
