摘要:

本研究旨在建立1种简单易行、获得细胞纯度较高的体外分离、培养大鼠脑微血管内皮细胞的方法。取7~10日龄SD大鼠,分离大脑皮质,经Ⅱ型分散酶消化、葡聚糖3次离心法获得大鼠脑微血管段,用胶原/分散酶消化后,在37 ℃ 5% CO2 培养箱中进行原代细胞培养。利用第Ⅷ因子相关抗原免疫荧光检测法,结合细胞形态学观察对培养的细胞进行鉴定。成功分离培养了大鼠脑微血管内皮细胞,倒置显微镜下单个细胞呈短梭形或多角形,汇合后呈铺路石样,单层贴壁生长;免疫荧光检测第Ⅷ因子相关抗原呈阳性。本试验成功建立了分离纯度较高的大鼠脑微血管内皮细胞的体外培养方法。

Abstract:

To establish a simple and feasible method for isolation of highly purified rats brain microvascular endothelial cells(RBMECs)from 7-10 days SD rats,the relatively pure cerebral microvessel fragments were obtained by careful dissection in dispase II and three times centrifugation with dextran.After digested with collagenase/dispase enzyme,cells were grown in a humidified atmosphere of 5% CO2 at 37 ℃,then were identificated by the factor Ⅷ-related antigen.The results showed that primary endothelium cells formed monolayers with the characteristic cobble-stone morphology and were strongly positive for Ⅷ-related antigen factor.It was indicated that relatively pure primary culture of RBMECs was successfully established using this method.
