Identification of 2 novel genes developmentally regulated in the mouse aorta-gonad-mesonephros region.
The first adult-repopulating hematopoietic stem cells (HSCs) emerge in the mouse aorta-gonad-mesonephros (AGM) region at embryonic day 10.5 prior to their appearance in the yolk sac and fetal liver. Although several genes are implicated in the regulation of HSCs, there are gaps in our understanding of the processes taking place in the AGM at the time of HSC emergence. To identify genes involved...
متن کاملInterleukin-1-mediated hematopoietic cell regulation in the aorta-gonad-mesonephros region of the mouse embryo.
Hematopoiesis during development is a dynamic process, with many factors involved in the emergence and regulation of hematopoietic stem cells (HSCs) and progenitor cells. Whereas previous studies have focused on developmental signaling and transcription factors in embryonic hematopoiesis, the role of well-known adult hematopoietic cytokines in the embryonic hematopoietic system has been largely...
متن کاملInterleukin-3 promotes hemangioblast development in mouse aorta-gonad-mesonephros region.
BACKGROUND The hemangioblast is a bi-potential precursor cell with the capacity to differentiate into hematopoietic and vascular cells. In mouse E7.0-7.5 embryos, the hemangioblast can be identified by a clonal blast colony-forming cell (BL-CFC) assay or single cell OP9 co-culture. However, the ontogeny of the hemangioblast in mid-gestation embryos is poorly defined. DESIGN AND METHODS The BL...

متن کاملBrief report Polarized expression of bone morphogenetic protein-4 in the human aorta-gonad-mesonephros region
In the mammal, definitive hematopoietic stem cells (HSCs) are first derived from mesodermal cells within a region of the embryonic para-aortic splanchnopleura known as the aorta-gonad-mesonephros (AGM). Within this region, HSCs are thought to arise from hemangioblast precursors located in the ventral wall of the dorsal aorta. However, the factors that regulate HSC development in vivo are still ...
