摘要 目的建立一种能大量分离人脐静脉内皮细胞(human umbilical vein endothelial cells,HUVECs)体外培养模型,并对其进行鉴定,为体外血管内皮细胞及相关疾病的研究搭建桥梁。方法采用0.1%Ⅰ型胶原酶分离脐静脉内皮细胞,于M199培养基(含20%胎牛血清,80%M199不完全培养基,1%终浓度为50μg/mL内皮细胞生长复合物,1%终浓度为100μg/mL肝素钠,1%青-链霉素,1%L-谷氨酰胺)中培养,待细胞80%以上融合后,用0.25%的胰酶和0.25%的EDTA消化传代,并在倒置显微镜下观察细胞形态,用免疫荧光法对细胞进行鉴定。结果原代培养的HUVECs在24 h后完全贴壁,2~3 d可达80%的融合,倒置显微镜下观察细胞呈鹅卵石状排布,免疫荧光显示细胞胞浆中Ⅷ因子相关抗原阳性。结论 0.1%Ⅰ型胶原酶消化HUVECs方法便于操作,细胞获得量多且生长状态良好。
