Yohei Kawano等人建立了一种新的可保持小鼠淋巴祖细胞长期增殖的培养系统,不需要进行任何基因操作。

该方法培养的淋巴样祖细胞在体内外均可分化成淋巴系细胞和粒系细胞。

摘要:

普通的淋巴样祖细胞(CLP)可分化成T淋巴细胞、B淋巴细胞、树突状细胞、天然杀伤细胞和固有淋巴细胞。

Yohei Kawano等人首次提出一种培养条件,可建立淋巴细胞限制性的长期增殖的CLP细胞系和从正常小鼠骨髓中获得的细胞克隆,而且不需要任何的遗传操作。该条件培养的CLP克隆的细胞,大多数仍可在体外被诱导分化成T细胞、B细胞、NK、DC和髓系细胞。将培养的CLP细胞,移植到活体内,可迅速的填充到宿主体内,并分化成全淋系细胞和粒系细胞。

该简单的方法可获得大量的培养的无限制的CLP细胞,为研究调控淋巴细胞分化过程的内源性和外在性因素提供便利。如果该方法可应用于人类CLP,则可为需要进行骨髓淋巴细胞重建的患者提供新的细胞治疗的机会。
