摘要
小鼠单核巨噬细胞白血病细胞(RAW264.7)是通过Abelson鼠白血病病毒诱导BALB/c小鼠产生肿瘤后得到的细胞株。RAW264.7细胞在医学研究中应用十分普遍:它是许多白血病相关研究模型的常用细胞株;在微生物学、免疫学等研究中也十分常用;同时也是小鼠源性破骨前体细胞,可通过特定细胞因子的诱导在体外获得成熟破骨细胞,因此也成为许多骨骼疾病研究的体外模型。但RAW264.7细胞形态和分化状态多变,在实际培养中较难把握,给科研工作带来了一定困难。科研工作者在RAW264.7细胞的培养方法、细胞的形态及分化状态等方面始终观点不一,对于用RAW264.7细胞在体外诱导获得破骨细胞的方法也有许多差别。本文结合文献资料及实践,探索了RAW264.7细胞的培养条件,冻存、复苏、传代方法,以及用核因子κB受体活化因子配基(receptor activator for nuclear factor-κB ligand,RANKL)诱导其成为成熟破骨细胞的技术关键;旨在总结RAW264.7细胞的培养及诱导其分化为破骨细胞的经验教训,探讨RAW264.7细胞的培养和在体外用RANKL诱导RAW264.7细胞分化为破骨细胞的方法、技巧,供广大科研工作者借鉴。
