在这里,我们描述了一种新的流式细胞术方法,用于直接从新鲜小鼠骨髓和脾脏中前瞻性分离早期爆发形成单位红系(BFU-e)和集落形成单位红系(CFU-e)祖细胞。该协议基于单细胞转录组学数据开发,是第一个以高纯度分离所有组织红系祖细胞的方案。
该协议允许直接从新鲜收获的小鼠组织(如骨髓和脾脏)中鉴定和分离BFU-E和CFU-E红系祖细胞。使用这种技术,我们可以分离出纯粹的红系祖细胞群,这在以前的流动方案中是不可能的。这种方法通过允许在许多下游实验中分离祖细胞,极大地增强了我们研究红系疾病小鼠模型的能力。
首先,将新鲜解剖的股骨和胫骨直接放入冷染色缓冲液或SB-5中,并将管子放在冰上,直到准备好提取骨髓。将干净的消毒砂浆放在桶中的冰上,然后将骨头转移到研钵中。使用解剖剪刀,剪掉每根骨头的大约 1 毫米末端。
