Bone marrow-derived mesenchymal stem cells are capable of chondrogenesis, making them a possible source of cells for injectable cartilage tissue engineering. There exist different ideas on the ability of mesenchymal stem cells's chondrogenesis in monolayer culture. Because of this, the effect of adult rabbit's bone marrow-derived mesenchymal stem cells chondrogenesis in monolayer culture was studied. The mesenchymal stem cells was isolated from adult rabbit's bone marrow and monolayer cultured. TGF-β1, Vit-C and Dexamethasone were used. Immunohistochemistry analyses and histological staining of H-E, Methylaniline blue and Alcian blue were performed to identify the expression of collagen type Ⅱ and cartilage associated matrix. The results showed that the induced cells expressed and produced collagen type Ⅱ and cartilage associated matrix. This suggests that the differentiation of adult rabbit's marrow-derived mesenchymal stem cells into chondrocyte in monolayer culture is feasible and may be induced by TGF-β1, Vit-C and Dexamethasone.

骨髓基质干细胞的软骨分化潜能使其可能成为可注射组织工程化软骨研究的种子细胞，为探讨体外培养的骨髓基质干细胞在平面诱导条件下软骨分化的可行性，我们进行下列实验：获取并体外平面培养成体兔骨髓基质干细胞，应用TGF-β〓、Vit-C和地塞米松对其软骨分化诱导，诱导后的骨髓基质干细胞行细胞爬片组织学和Ⅱ型胶原免疫组化，结果证实，诱导后骨髓基质干细胞可分泌Ⅱ型胶原，组织学染色可见类似于软骨细胞，由此证明体外培养的骨髓基质干细胞在平面诱导条件下可以软骨分化，其软骨诱导因子为TGF-β〓、Vit-C和地塞米松。
