Web4 feb. 2024 · HSC niches can be defined based on their anatomical location in the BM and the type of blood vessel they contain [arterioles , sinusoids , or transition zone vessels ]. To date, there are two anatomically and functionally distinct niches that dictate HSC cell fate in mouse BM: 1) the central niche, which is located in the inner BM, and 2) the endosteal … WebMegakaryocytopoiesis is the process by which megakaryocytes and ultimately platelets develop. As with erythropoiesis, the sites of megakaryocytopoiesis change during embryonic and fetal development. In mouse development, megakaryocytes have been identified in the early yolk sac (McGrath and Palis, 2005).
