Staining extent and intensity were evaluated semiquantitatively and mean values for each parameter were calculated. Immunostaining with D2-40 showed positivity in 100% of skeletal myxoid chondrosarcomas, 96% of enchondromas, 95% of low-grade chondrosarcomas, 80% of chordoid meningiomas, and 75% of chordoid gliomas. Staining with S100 demonstrated diffuse, strong positivity in all (100%) chordoid gliomas, skeletal myxoid chondrosarcomas, low-grade chondrosarcomas, and enchondromas, 94% of chordomas, and 81% of extraskeletal myxoid chondrosarcomas, with focal, moderate staining in 40% of chordoid meningiomas.

Elastic fibers were well-distributed,and vascular endothelial cell did not immigrate.We suggested that expression of ectogenic VEGF triggered paracrine and autocrine of VEGF of chondrocyte and co-acted with VEGF receptor 2 to enhance permeability of chondrocyte and improve internal construct of engineering cartilage,and prevent vascularize proceed.
转VEGF基因软骨细胞作为组织工程的种子细胞与pluronic F-127复合后可于裸鼠体内形成转基因组织工程软骨,与对照组相比,转VEGF基因组织工程软骨具良好的生物学特性,结构均一且与正常软骨组织相似,软骨ECM的GAG、COLⅡ、COLⅩ增多,RunX2、Sox9表达增高,细胞处于增生期的肥大状态,初步分析其原因可能是转染后外源性的VEGF持续表达触发了软骨细胞VEGF自分泌,并通过VEGFR-2作用于软骨细胞,提高了软骨细胞活性,促进其存活与增殖,但未在软骨组织内引起血管内皮细胞的迁移及小血管形成。

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。

The human cartilages are composed of chondrocyte and extracellular matrix,the form of chondrocytes are hypertrophy and the quantity are less;the ECM of cartilage are compised of type II collagen and proteoglycan. Articular cartilages are all hyaline with little fibers. Trauma and arthritis are the main cause of cartilage injury,the ommilayer injury ofcartilage can be recovered by marrow,but because of without stimulation mechanism,the new tissues are merely fibrocartilages,they can not be coincide with hyaline cartilage in menchanics;the purely damage of articular cartilage can not stimulate chondrocyte to regenerate because of without blood circulation,thus,the plerosis of articular catilage can not depend on the proliferation of local chondrocyte.Ever since,people tried their best to find a way to reconstruct articular cartilage.
造成人体关节软骨损伤的原因主要为创伤和关节炎,关节软骨全层损伤可由于骨髓中间充质干细胞的高速增殖修复,但这种修复由于缺乏相应的刺激机制,只能形成纤维软骨,而不能形成符合关节生理、力学要求的透明软骨;单纯软骨部分损伤软骨组织内无血管,软骨细胞迁移迟缓,无法使损伤区域软骨细胞再生,因此,关节炎及关节创伤后的软骨修复不能依赖于软骨细胞的增殖和迁移。

Both Fas and NO can lead chondrocyte apoptosis respectively and cause articular cartilage destruction. IGF-Ⅰ, TGF-β, bFGF, BMP and other growth factors are polypeptide agents that can influence cell activity by signal convection. They can accelerate chondrocyte proliferation and proteoglycan synthesis, play the local regulation action on formation and plerosis of bone and cartilage tissue by autocrine or paracrine. They have the ability to induce cartilage formation. Some investigations showed that growth factors can influence chondrocyte metabolism, synthesis of specific Ⅱ type collagen and proteoglycan by co-operation and inhibition. 1. 3 Situation of OA therapeutics The therapeutic methods of OA mainly comprised non-drug treatment, drug treatment, operation treatment, tissue and genetic engineering, et al. Drug treatment is the chief method among them.
若其活性发生改变,则将导致关节软骨基质成分的丢失和进行性破坏;软骨细胞凋亡与OA的发病密切相关,Fas与NO可各自独立介导软骨细胞凋亡,造成关节软骨破坏;IGF-Ⅰ、TGF-β、bFGF、BMP等生长因子是一组通过细胞间信号传递影响细胞活动的多肽因子,具有促进细胞生长、增殖与合成等作用,可通过自分泌或旁分泌方式对骨和软骨的形成和修复起局部调节作用,可促进软骨细胞增殖、分化与蛋白多糖的合成,具有较强的诱导软骨形成的能力,研究表明多种生长因子相互促进、相互抑制,以协同或拮抗方式影响软骨细胞代谢,影响软骨细胞特异性Ⅱ型胶原和蛋白多糖的合成分泌。
