来源:Er, S. 等人。研究原代胚胎小鼠中脑多巴胺神经元中预先形成的原纤维诱导的 α-突触核蛋白积累。J. Vis. Exp.(2020 年)。
该视频演示了从小鼠胚胎的中脑中分离和培养多巴胺神经元的过程。孤立的腹侧中脑底板使用酶解离。收获产生的多巴胺神经元并转移到多孔板内的微岛中。将细胞与多巴胺神经元培养基一起孵育,以将细胞保持在微岛内的高密度。
所有涉及样本采集的程序均已按照研究所的 IRB 指南执行。
1. 准备工作
2. 从胚胎第 13.5 天 (E13.5) 小鼠胚胎中分离腹侧中脑底
3. 从 96 孔板格式的 E13.5 小鼠胚胎中建立原代胚胎中脑培养物

图 1:从 E13.5 小鼠胚胎中解剖中脑底。 (A) 头部后躯的切割位置用黑色箭头和白色虚线标记。(B) 从胚胎的其余部分取出该碎片。移除的棋子被圈出。(C) 将作品旋转 90°,使其面向观察者的后部。(D) 该块从黑色箭头打开,从尾部到颅骨(用白色虚线标记)。(E) 从开口下方 0.5 mm–1 mm 处,切割 2 mm2 –4 mm2 区域(用黑线标记)。(F) 腹侧中脑底被隔离(用黑色虚线方块标记)。比例尺 = 1 毫米。
