文题释义:
人脑微血管内皮细胞:是血脑屏障的主要组成成分,能够限制可溶性物质和细胞等从血液进入大脑。大脑微血管内皮细胞与外周内皮细胞相比具有一些相同特性。
紧密连接:由分支状封闭索网络组成,每条封闭索独立于其他封闭索作用。因而,紧密连接防止离子通过的能力随封闭索的数目指数式增长。每条封闭索由一列嵌入两个原生质膜的跨膜蛋白构成,蛋白的胞外结构域使其彼此间一个个直接相联。尽管还有其他蛋白存在,两种主要类型的蛋白是密封蛋白和闭合蛋白,它们与位于细胞膜内侧的不同的把封闭索锚定到肌动蛋白细胞骨架的外周膜蛋白相联。因此,紧密连接连起了相邻细胞的细胞骨架。
摘要
背景:
脑微血管内皮细胞是神经科学研究领域的重要工具细胞,如何获得高纯度的脑微血管内皮细胞一直是体外研究的关键和难点。
目的:探索一种简便易操作,高纯度的原代脑微血管内皮细胞的分离培养方法。
方法:使用6-8周龄C57BL/6小鼠,经酶消化及梯度离心法获得微血管段,使用药物进一步纯化内皮细胞,利用CD31和GFAP免疫荧光染色鉴定内皮细胞纯度。使用Claudin-5免疫荧光染色鉴定紧密连接蛋白的表达情况。
结果与结论:①细胞呈旋涡状或铺路石样排列、生长;②免疫荧光显示内皮细胞纯度达99%以上,并广泛表达紧密连接蛋白;③结果表明,实验建立了一种简便、易操作的,可以获得大量高纯度的原代小鼠脑微血管内皮细胞的培养方法。

Abstract:

BACKGROUND: Brain microvascular endothelial cells (BMECs) are important tools in the field of neuroscience research; therefore, how to obtain highly purified BMECs is a key and difficulty in vitro.
OBJECTIVE: To develop a simple method of isolating and culturing highly purified BMECs.
METHODS: C57BL/6 mice aged 6-8 weeks old were selected, and microvessels were obtained using enzyme digestion and gradient centrifugation. Further, endothelia cells were purified by certain drugs, followed by identified by CD31 and GFAP immunofluorescence staining. The expression of Claudin-5 was detected using immunofluorescence staining with anti-Claudin-5 antibody.
RESULTS AND CONCLUSION: Mouse BMECs grew and arranged in spiral or cobblestone-like. Immunofluorescence staining showed that the purity of BMECs reached above 99% and Claudin-5 was highly expressed. In conclusion, a simple method of easy accessibility is developed to obtain highly purified primary mouse BMECs.
