Background And Purpose

第一个成体型造血干细胞(HSCs)位于主动脉-性腺-中肾(AGM)区域,由造血内皮细胞产生。胚胎头部是造血干细胞发育的另一个部位。野生型p53诱导磷酸酶1 (Wip1)是一种ii型δ家族丝氨酸/苏氨酸磷酸酶,参与各种细胞过程,如淋巴细胞发育和成体造血干细胞的分化。最近,我们发现Wip1调控AGM区的HSC的成熟。然而,目前尚不清楚Wip1是否调控胚胎头部的造血功能。

Method

流式细胞术,造血干细胞移植,Real-time PCR, CFU-C集落形成实验

Conclusion

Wip1正向调控头部造血细胞干祖细胞发育

Main results

Wip1缺失导致胚胎头部造血祖细胞数量的减少。体内移植实验显示,Wip1缺失后HSC功能下降。我们证实,Wip1的缺失降低了胚胎头部小胶质细胞的比例和细胞数量。进一步观察发现,Wip1缺失可增强小胶质源性促炎因子的基因表达。
