The extracellular matrix wasstained positively for Alcian blue, Toluidine blue and Safranin O / FastGreen at 7 and 14 days after initial chondrogenic induction of adipose -derived mesenchymal stem cells, and indicated collagenⅡand aggrecanwere expressed positively.

2脂肪间充质干细胞在高密度的"微团"培养条件下，于诱导7、14天后阿尔新兰染色、甲苯胺兰染色、藩红0／固绿染色阳性，诱导4、7、14天后Ⅱ型胶原蛋白免疫细胞化学、aggrecan免疫荧光阳性表达。

METHODS: In the experimental group, ADSCs were cultured with the scaffold and induced by CDMP1(50 μg/L) in basic medium for another 2 weeks. In the control group, SD rat cartilage cells were cultured with elementary nutrient liquid with scaffold for another 2 weeks. Twenty nude mice were imbedded the composite of cells-scaffold of the experimental group in their left armpits and the composites of cells-scaffold of the control group in right armpits. Every ten nude mice were killed at 8 and 12 weeks and were examined by safranine O-fast green and toluidine blue staining.

体外培养的脂肪干细胞复合于支架上，加入诱导液(基础培养液+ 50 μg/L软骨形态发生蛋白1)继续培养2周作为实验组；将SD仔鼠软骨细胞复合于支架上，常规培养2周作为对照组。20只裸小鼠，左侧腋窝皮下均植入实验组细胞-支架复合物，右侧腋窝皮下均植入对照组细胞-支架复合物。8， 12周各处死10只，行甲苯胺蓝和番红O-固绿染色。

A new parallel-epiphyseal cartilaginous tissue was found in the subcutaneous tissue 4 weeks after operation. The tissue was stained with HE, toluidine blue, safranine O and collagenⅡ. A large number of chondrocytes and a cartilage lacuna-like structure were observed under a microscope with no obvious inflammatory reaction around the calcium alginate and polylysine microspheres.

结果 体外培养时微球中骺板细胞生长、增殖情况良好；移植皮下后第4周取材可见外形呈类骺软骨样组织块，行HE、甲苯胺蓝、番红"O"及Ⅱ型胶原等染色，镜下观察可见大量软骨细胞及类软骨陷窝样结构，植入的海藻酸钙微球周围组织无明显炎症反应。
