The effects of advanced glycation end products (AGE) of the Maillard reaction on proliferation, migration and angiogenesis of cultured human umbilical vein endothelial cells (HUVEC) were studied. In an in vitro angiogenesis system, tube formation of HUVEC was dose-dependently stimulated by AGE at 0.5-50 micrograms/ml. Migration of HUVEC was also stimulated by AGE in a similar concentration range, and checkerboard analysis revealed that AGE were chemotactic but not chemokinetic. Proliferation of HUVEC was not affected by AGE. These data provide evidence that AGE are angiogenic.
研究了美拉德反应的晚期糖基化终产物(AGE)对培养的人脐静脉内皮细胞(HUVEC)增殖、迁移和血管生成的影响。在体外血管生成系统中,0.5 - 50微克/毫升的AGE以剂量依赖方式刺激HUVEC形成管腔。在相似浓度范围内,AGE也刺激HUVEC迁移,棋盘分析显示AGE具有趋化性而非化学促动性。HUVEC的增殖不受AGE影响。这些数据证明AGE具有血管生成作用。
