WebNov 19, 2015 · The AGM region is considered the predominant site of de novo generation of HSCs in mice. We determined whether the HSC defect in ATF4 −/− FL was caused by insufficient generation of HSCs in the AGM region. At E11.5, the ATF4 −/− AGM region contained slightly fewer cells than the ATF4 +/+ AGM region ( Figure 2A ). WebFeb 14, 2006 · The AGM region is the first intra-embryonic area where haematopoietic stem cells (HSCs) capable of colonizing adult bone marrow have been detected ( 2 ). The HSCs in the AGM region divide more rapidly than those in the extra-embryonic tissue, which is consistent with an important role for the AGM in embryonic haematopoiesis.
