中文摘要
我们成功地在动物模型上移植了骨髓间充质干细胞(MSC),并成功地修复了软骨和/或骨缺损。此外,DEC1基因在人MSC中的强制表达可促进体外培养的软骨细胞分化,DEC1基因强制表达可抑制成肌和成脂分化,促进成软骨细胞分化。此外,抑制膜结合的转铁蛋白样蛋白(MTF)在间充质细胞中的表达也促进了软骨分化。各种生长因子和低氧刺激MSC培养中MTF、DEC1和/或DEC2的表达。提示DEC1、DEC2或MTF基因修饰的骨髓间充质干细胞可用于再生医学。
英文摘要
We succeeded in regeneration of cartilage and/or bone defects after transplantation of bone marrow mesenchymal stem cells (MSC) in animal models. In addition, forced expression of DEC1 gene in human MSC stimulated chondrocyte differentiation in vitro, DEC1 forced expression suppressed myogenic and adipogenic differentiation and enhanced chondrogenic differentiation. Furthermore, foiled expression of membrane-bound transferrin-like protein (MTF) in mesenchymal cells also enhanced chondrogenic differentiation. Various growth factors and hypoxia stimulated the expression of MTF, DEC1 and/or DEC2 in MSC cultures. These findings suggest that MSC transfected with DEC1, DEC2 or MTF are useful for regeneration medicine.
