间充质干细胞 (MSC)广泛分布于各种不同的组织 ,在骨髓、外周血、脐血、脂肪、胎肺、胎肾等组织中均可分离培养出MSC ,MSC具有成骨、成脂、成软骨等多向分化潜能。另外 ,MSC还具有支持造血的作用 ,对造血干细胞有扩增作用 ,共移植MSC可以促进造血干细胞的植入。临床上MSC可望用于组织工程和细胞工程的种子细胞及基因治疗的靶细胞等 ,具有广阔的应用前景 Mesenchymal stem cells (MSCs) are widely distributed in various tissues. MSCs can be isolated and cultured in bone marrow, peripheral blood, cord blood, fat, fetal lung, fetal kidney and other tissues. MSCs possess osteogenic, adipogenic, Into cartilage and other multi-directional differentiation potential. In addition, MSC also has the function of supporting hematopoiesis and has an expansion effect on hematopoietic stem cells. Co-transplantation of MSCs can promote the implantation of hematopoietic stem cells. Clinical MSC is expected to be used in tissue engineering and cell engineering seed cells and gene therapy target cells, etc., has broad application prospects
