Primitive and definitive hematopoiesis
WebApr 11, 2015 · The study of in vivo hematopoietic development in humans is less understood relative to the mouse model due to limitations in experimental approaches. However, evidence resulting from studies in the human embryo has indicated that definitive HSCs emerge in the embryo proper from aortic endothelium similar to observations made … WebMay 13, 2024 · Finally, we have introduced the idea that primitive hematopoiesis consists of the specification of unipotent hematopoietic precursors; whereas, definitive hematopoiesis initiates with the specification of multipotent precursors [29, 30], independent of previously admitted criteria.

To further characterize the CD43+ hESCs-derived HPCs in detail, we applied pseudotime analysis to order all the hESC-HPCs based on their transcriptional profiling (Fig. 2a). Known genes that encode markers or regulators for human HSPCs such as CD34, CD90, MYB, RUNX1, GFI1, IKZF1, HOXA9, and … See more Since the cell surface marker CD44 and GATA1 are almost mutually exclusive in their expression and display opposite patterns during pseudotime … See more Examining lineage fate potential at the single-cell level is a golden standard to assess the multi-potency of HSPCs.

Web3,4 In the embryo proper, definitive HSCs first emerge in the aorta-gonad-mesonephros (AGM) region of both humans and mice as well as the vitelline and umbilical arteries of the murine embryo. 5,6 Additionally, primitive HSCs have also been found in the placentas of humans and mice indicating that extra-embryonic tissue may also be an important … WebHematopoiesis is the process that generates all the body’s blood cells. In vertebrates, hematopoietic development occurs in two phases: a transitory embryonic, or primitive, wave produces only erythrocytes (red blood cells) and myeloid cells; an adult, or definitive, wave gives rise to at least three blood cell lineages,
