摘要: 目的 探讨不同比例兔成骨细胞(ROB)与血管内皮细胞(RVEC)直接联合共培养后,对成骨细胞功能的影 响。方法 取兔成骨细胞与血管内皮细胞,将两者分为4组分别以1∶0、1∶1、2∶1、4∶1直接联合共培养于培养皿中, 通过对细胞内碱性磷酸酶活性(ALP)测定和培养液中骨钙素(OC)定量测定,观察血管内皮细胞对成骨细胞功能的 影响。结果 成骨细胞与血管内皮细胞直接联合共培养相容性良好,2∶1的细胞比例组ALP活性及OC含量较其 他各组明显增高。结论 在体外直接联合共培养的体系中,血管内皮细胞有明显促进成骨细胞活性的作用。

Abstract: Objective The purpose of this study was to observe the influence on proliferation of rabbit osteoblast (ROB) of rabbit vascular endothelial cell(RVEC) co-culturedwith rabbit osteoblast (ROB).Methods Rabbit osteoblasts and rabbit vascu- lar endothelial cells in ratio of 1∶0,1∶1,2∶1,4∶1were selected to co-culture.The function of osteoblasts was assessed by alkaline phosphatase(ALP) activity and osteocalcin(OC) assay.Results There was good compatibilitywhen osteoblasts and vascular en- dothelial cells were co-cultured. The activity ofALP and OC in the group of ROB and RVEC co-cultured in ratio of 2∶1 was higher than that of the other three groups.Conclusion In direct co-culture systemin vitro, RVEC can improve activity of ROB.
