造血干/祖细胞 (HSPC) 在发育过程中发生位置转变,并在哺乳动物的整个生命周期中循环,在归巢、植入和保留的连续步骤中进出血流以参与骨髓 (BM) 生态位。我们在此表明​​,胎儿发育中 BM 的 HSPC 植入依赖于鸟嘌呤核苷酸结合蛋白刺激 α 亚基 (Gsα)。成年 Gsα−/− HSPC 分化并经历趋化性,但也不会归巢或植入成年小鼠的 BM 中,并且表现出明显无法参与骨髓微血管系统。如果在植入后删除,Gsα 不会导致骨髓中缺乏保留,而是细胞因子诱导的血液动员受到损害。测试 Gsα 的激活是否影响 HSPC,药理学激活剂增强体内归巢和植入。 Gsα 控制体内生理条件下 HSPC 定位的特定方面,并可能在药理学上靶向提高移植效率。
Hematopoietic stem/progenitor cells (HSPC) transition in location during development and circulate in mammals throughout life, moving into and out of the bloodstream to engage bone marrow (BM) niches in sequential steps of homing, engraftment and retention. We show here that HSPC engraftment of BM in fetal development is dependent upon the guanine nucleotide binding protein stimulatory alpha subunit (Gsα). Adult Gsα−/− HSPCs differentiate and undergo chemotaxis, but also do not home to or engraft in the BM in adult mice and demonstrate marked inability to engage the marrow microvasculature. If deleted after engraftment, Gsα did not lead to lack of retention in the marrow, rather cytokine-induced mobilization into the blood was impaired. Testing whether activation of Gsα affects HSPC, pharmacologic activators enhanced homing and engraftment in vivo. Gsα governs specific aspects of HSPC localization under physiologic conditions in vivo and may be pharmacologically targeted to improve transplantation efficiency.
