Web1 apr. 2012 · Extramedullary haematopoiesis (EMH) refers to the development of haematopoietic tissue outside the bone marrow and normally occurs in the reticulendothelial system (liver, spleen and lymph nodes). The involvement of other parenchymatous organs is rare and there are only sporadic reports concerning the kidney [ 1–7, 8 ]. WebIn the second trimester, hemopoiesis (also called hematopoiesis) occurs primarily in the developing liver, with the spleen playing a minor role ( Figure 13–1 ). Skeletal elements begin to ossify and bone marrow develops in their medullary cavities, so in the third-trimester marrow of specific bones becomes the major hemopoietic organ. FIGURE 13–1

WebThe stages of this process in mice are distinguished based on cell surface markers as shown in Figure 1, with similar stages defined in humans (Casero et al. 2015; Canté-Bar-rett et al. 2024). The stroma of the thymus remains rela-tively constant over long periods of time as multipotent hematopoietic precursors enter it in cohort after cohort, Haematopoietic stem cells (HSCs) reside in the medulla of the bone (bone marrow) and have the unique ability to give rise to all of the different mature blood cell types and tissues. HSCs are self-renewing cells: when they differentiate, at least some of their daughter cells remain as HSCs so the pool of stem cells is not depleted. This phenomenon is called asymmetric division. The other daughters of HSCs (myeloid and lymphoid progenitor cells) can follow any of the other differentiat…
