Hematopoietic stem and progenitor cells(HsPCs)are a subset population of multi-potent cells with self-renewal capability and differentiation into all lineages of blood cells(Zhang and Liu,2024).HSPCs arise from the ventral wall of embryonic dorsal aorta,the hemogenic endothelium in the aorta-gonad-mesonephros(AGM)region,tightly controlled by epigenetic,transcriptional,and signaling networks(Wu and Hirschi,2021).However,how developmental hemogenic endothelium performs cell fate surveillances during HSPC emergence and efficiently eliminates them to avoid abnormal hematopoiesisremainselusive.
