摘要
目的 :通过Ⅱ型胶原诱导鼠关节炎 (CIA)动物模型的建立 ,研究探讨CIA小鼠关节组织提取物对内皮细胞增殖影响及抗血管内皮生长因子 (VEGF)中和抗体对其抑制影响。方法 :采用完全无血清培养、用3H TaR掺入技术检测CIA小鼠关节组织提取物及抗VEGF中和抗体对体外培养人脐静脉内皮细胞 (HUVEC)增殖影响。结果 :发现在CIA小鼠关节组织提取物及小鼠VEGF(mVEGF)作用下 ,培养的HUVEC增殖明显 ,并被抗VEGF中和抗体所抑制 ,抑制率分别为 :6 9 9%、72 2 %。结论 :CIA关节炎形成早期关节组织内可能含有大量的VEGF ,并以较强的生物活性形式存在。同时提示 ,VEGF刺激大量滑膜细胞增殖、血管新生、滑膜炎形成 ,VEGF可能是CIA形成过程中关键性炎症介质。
Objective:To investigate the effects of extracts of aqueous joint during CIA development on the HUVEC proliferation in vitro and expression of VEGF Methods: 3H TaR incorporation was used to estimate the HUVEC proliferation by extracts of aqueous joint and VEGF, and was used cultured in an absolutely serum free medium Results:Extracts of aqueqous joint during CIA development stimulated proliferation of HUVEC and this proliferation was inhibited by the anti VEGF neutralizing antibody Conclusion:The expression of VEGF in the extracts of the aqueous joint during an early stage of CIA development increased and expressed biologically active
