摘要 目的:研究骨髓干细胞向心肌梗死区迁移归巢的机制,探讨其对心肌梗死的作用。方法:制备大鼠心肌梗死模型,梗死心肌边缘区注射血管内皮生长因子(VEGF),病理学检测心肌梗死后心肌细胞分泌的细胞因子变化及其与CD34+骨髓间充质干细胞(BMCs)迁移归巢之间的关系。结果:心肌梗死后1 d VEGF表达最高(2 351±112)pg/m l,随时间的推移,7 d时降至(1 875±87)g/m l(P<0.01),其浓度迅速降低,至14 d时已降至(212±95)pg/m l,假手术组始终无VEGF的表达;在心肌梗死区边缘局部注射VEGF后24 h可见CD34+BMCs数为(24.4±5.2)个/HP,未注射VEGF的心肌梗死区也可见CD34+骨髓干细胞浸润,但CD34+BMCs数仅为(7.5±2.0)个/HP,P<0.01;心肌梗死后14 d,注射VEGF组与未注射组心肌梗死区毛细血管密度分别为(11.38±1.31)和(3.12±1.32),P<0.01。结论:在心肌梗死区边缘局部注射VEGF,可以促进CD34+BMCs向心肌梗死区归巢,可能参与毛细血管增生和坏死心肌的修复。
