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。

Results Positive staining for VEGF was distributed mostly in osteoblasts, osteoclasts and newly-born osteocytes. Vascular endothelial cells and bone marrow cells also showed VEGF positive reaction. Hypertrophic chondrocytes in calcifying region of chondroephysis were VEGF positive, but VEGF was absent from chondrocytes in other zones of chondroephysis.

结果 VEGF阳性反应主要见于成骨细胞、破骨细胞及新生骨细胞中，血管内皮细胞及骨髓细胞也呈阳性反应；骺软骨钙化区肥大的软骨细胞为VEGF阳性反应，但其它区域的软骨细胞中无VEGF表达。

The capacity of endothelial cells to recognize and migrate in response to the extracellular matrix depends on one or more members of the integrin family of cell adhesion receptors.

血管新生的过程依赖于参与血管生成的细胞因子和细胞粘附的协同作用，整合素是一组细胞表面受体，介导细胞-细胞间、细胞-基质间的相互作用，对内皮细胞的粘附、迁移、增殖起重要作用。

Result: 1 HE staining 2 immunohistochemical method:①the positive expressive rate of Bax in proliferative phase and involuting phase of hemangioma, normal skin tissues in turn were

结果 1 HE染色：增生期血管瘤组织中可见条索状或片状内皮细胞增生，其间有不规则的内皮间隙和完整的血管腔，内皮细胞核肥大而淡染。

Since an excessive cell growth is considered as the main pathological event, cell proliferation model occupy most of the animal models, and these cells include retinal pigment epithelial cell, fibroblast cell, cartilage cell and vascular endothelial cell.

由于PVR的主要病理变化是细胞的过度增生，因而动物模型多以细胞增生模型为主，细胞种类有视网膜色素上皮细胞、成纤维细胞、软骨细胞、血管内皮细胞等。
