Perceptively on 3d and 5d. Collagen is positive in Western blot on 9d. Aniline dyeing is positive on 12d. The control group was negative. Ad-BMP-2 transferred MSCs cultured in fibrin gel was positive in Aniline dyeing, Immunohistochemical. The therapy effect of group was better in histology, biochemistry and biomechanics in all periods than the other two groups, and was similar to the natural cartilage.

结果 ①Ad-BMP-2转基因MSC BMP-2、CollagenⅡ的PT-PCR分别在3、5d呈阳性，CollagenⅡ的Western Blot 9d为阳性，较对照组有显著差异；②转基因MSC经纤维蛋白体外三维培养后免疫组化和苯胺蓝染色呈阳性，电镜显示细胞生长良好，有基质合成；③转基因修复组各时期大体、组织形态学和组织化学成份均显著优于其它两组，12W时力学和组织学已接近正常关节软骨。
