Tissue engineering skin has a wide application prospect on the clinical treatment of all sorts of skin defect, especially large area burn. The shortage of seed cells and their function improvement are the main problems in this field. The existing seed cells of tissue engineering skin are difficult to meet the needs of clinical application due to the limitations of acquisition, proliferation, and aging. Subsequently, the generation of induced pluripotent stem cells (iPSCs) provides a safe and efficient cell source for tissue engineering skin. Our article focuses on the origin of iPSCs and its characteristics of differentiating into keratinocytes, fibroblasts, melanocytes, vascular smooth muscle cells, nerve cells, and hair follicle, and discusses the main problems and prospects of iPSCs in establishment of tissue engineering skin and application in wound repair.
组织工程皮肤在各种皮肤缺损特别是大面积烧伤的临床治疗上具有广泛的应用前景，而种子细胞来源不足及其功能完善是目前该领域面临的主要难题。现有组织工程皮肤种子细胞由于获取、增殖及老化等方面的限制难以满足临床应用的需要。诱导多能干细胞的出现，为组织工程皮肤提供了安全高效种子细胞新来源。本文主要论述诱导多能干细胞的来源及其向角质形成细胞、成纤维细胞、黑素细胞、血管平滑肌细胞、神经元、毛囊分化等特性，并展望其在组织工程皮肤构建与创面修复应用中所面临的主要问题和前景。.
