血脑屏障完整性对神经系统功能至关重要。在果蝇黑色素仪中,血脑屏障是由胚胎发育晚期的胶质细胞形成的。该协议描述了在D.melanogaster胚胎和第三星幼虫中进行血脑屏障形成和维护的测定方法。
这种方法可以帮助回答有关血脑屏障在多阶段发育过程中形成和维持的遗传调控关键问题。这种方法也可以适应,以检查其他屏障的渗透性,如肠道上皮在各种生物体。该技术的主要优点是,它允许评估活组织中的血脑屏障功能。
此方法的可视化演示至关重要,因为示例操作可能很困难,并且许多步骤需要密切注意细节。对于胚胎收集的地方,至少50个处女与20至25雄性每瓶玉米餐阿加食物,并孵育这些苍蝇一到两天,然后再开始收集。前一天收集,热苹果汁加糖板在25摄氏度过夜。
