targeting of deep brain structures with microinjections for delivery of drugs, viral vectors, or cell transplants

进入脑实质Microinjections很重要的程序，以提供药物，病毒载体或细胞移植。注射针，在其运动轨迹会产生脑部病变是一个主要关注的不仅是大脑小，而且有时需要多次注射，特别是在老鼠大脑。我们在这里展示的方法，以生产50微米管腔，从而显着降低脑损伤，并允许一个精确的定位到啮齿类动物的大脑的玻璃毛细管针。此方法允许小卷交货（从20到100 NL），减少了出血的风险，并最大限度地减少药物进入脑实质的被动扩散。通过使用不同大小的毛细玻璃管，或改变针管腔，几种类型的物质和细胞可以被注入。用玻璃毛细管Microinjections代表在注射技术和针对最小的附带损害小老鼠的脑深部的一个显着的改善。
