Hematopoiesis evolution
WebI give a synopsis of the origin and determination of the hematocytoblast, beginning with a look at the hematopoietic organs that house hemocytoblasts in adult animals, followed by a more detailed overview of the embryonic development of the hematopoietic organ. Web1 feb. 2024 · It is established that mammals maintain hematopoiesis by the activity of thousands of hematopoietic stem and progenitor cells (HSPCs). 1 During human aging, the expansion of 1 or more HSPCs will result in clones that will sustainably contribute more than others to the production of mature blood cells ( Figure 1 ).
