Objective To culture and proliferate bone marrow mesenchymal stem cells (BMSCs) from bone marrow of SD rat in vitro, and to construct tissue-engineered skin with the cultured cells as well as tissue-engineered acellular dermal matrix.

• 目的:体外培养扩增SD大鼠骨髓间充质干细胞(bone marrow mesenchymal stem cells,BMSCs),复合组织工程化脱细胞真皮基质构建组织工程皮肤,为进一步临床应用奠定基础。
