To sum up, we first conclude that we can isolate mesenchymal stem cells from human fetal articular cartilage and they can be induced to differentiae into several cells under appropriate induction conditions. Anymore, they have their original tissue speciality. Therefore, we first report that mesenchymal stem cells of articular cartilage origin are superior to mesenchymal stem cells of bone marrow origin as seeding cells of cartilage tissue engineering and we provide a kind of new seeding cells of cartilage tissue engineering for the future clinic application.

Result showed that the epidermis dominant the morphogenesis changes. Mesenchymal is subdominant.β-catenin expression begin from horny placode epidermis stage and go up increasingly to peak value and maintain in hair follicle. The range of mesenchymal change is less.

结果表明，牦牛角的形态发生按照角基毛囊和角质外鞘发生与否分为5个阶段：角原基前期(Ed≤60)表皮增厚，无毛囊发生；角原基中期(Ed60~140)表皮持续增厚，有少量毛囊发生；角原基后期(Ed140~250)表皮变薄，大量毛囊发生；肉角期(≤0.5 a)真皮乳头发生；成角期(≥0.5 a)形成角质外鞘。

The result of Picric- sirius red polarized light method shows thatthe accrementition and reconstitution of mesenchymal fibers were markedly in experimental group compared with control group, especially in plantaris.Ⅰ-type collagen dominates in mesenchymal, IOD ratio ofⅠ/Ⅲchanged.

5天狼猩红-偏振光法提示在实验组骨骼肌间质纤维结缔组织明显增多尤其是在跖肌，以Ⅰ和Ⅲ型胶原增生为主，Ⅰ型胶原增生更为明显，Ⅰ型胶原与Ⅲ型胶原比值增高。

The up-regulation of the expression of MMP-9 perhaps takes part in the accrementition and reconstitution of mesenchymal fibers (Ⅰ-type collagen dominates in mesenchymal, IOD ratio ofⅠ/Ⅲchanged). MMP-9 can facilitate inflammatory cell infiltration, aggravate the development of CAM.

2MMP-9的增高可能参与了骨骼肌间质纤维增生及其构成的改变(Ⅰ和Ⅲ型增多，Ⅰ型胶原与Ⅲ型胶原比值增高)，诱导炎性细胞浸润，加重慢性酒精中毒性肌病的发生发展。

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。
