The aorta-gonad-mesonephros (AGM) region is an area derived from splanchnopleura mesoderm identified in embryonic humans, mice, and non-mammalian vertebrates such as birds and zebrafish.

WebBy day 11.5 of gestation, the AGM region is capable of autonomous initiation and expansion of definitive haematopoietic stem cells (HSCs). By day 12.5, HSC activity in the AGM region is reduced whilst a second wave of HSCs begins to emerge in the yolk sac. WebIt is now widely assumed that hematopoiesis in the yolk sac is "primitive" and that "definitive" hematopoiesis has its origins in the aorta/gonad/mesonephros (AGM) region. Recent studies of yolk sac hematopoiesis have challenged several aspects of this paradigm.

WebIt has long been believed that the origin derives from the extra-embryonic yolk sac. However, there is now considerable evidence that the first adult repopulating HSC is autonomously generated from a distinct region within the embryonic mesoderm, the aorta-gonad-mesonephros (AGM) region. 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 ).
