该视频演示了小脑切片的制备。它显示了从雏鸡胚胎中分离小脑的详细程序。然后使用组织切碎机从解剖的小脑制备切片,以进行进一步的实验分析。
所有涉及动物模型的程序均已由当地机构动物护理委员会和 JoVE 兽医审查委员会审查。
1. 鸡胚胎解剖第 14 天 (e14) 小脑
2. e14 小脑切片培养

图 1.从 E14 雏鸡胚胎中解剖小脑。(A) 将鸡蛋中的雏鸡斩首,将头取出,放入装有冰冷 PBS 的培养皿中。通过在眼睛和咽部后面做一个切口(虚线)来去除下颌和眼睛。(B) 去除颅骨表面的皮肤。(C) 去除额骨和顶骨,以及 (D) 从其周围的间充质和软骨中取出大脑。(E) 在解剖显微镜下,确定小脑在大脑后端的位置。在中脑和后脑之间切开(虚线),留下小脑和腹侧后脑。(F) 在小脑的外侧交界处(花梗)做切口,将小脑与后脑分开(虚线)。(G) 从小脑腹侧去除脉络丛(星号),直到留下一个完整的小脑并附有软脑膜。将小脑转移到冰冷的 HBSS 中,然后用组织切碎机准备切片。
