WebExtramedullary hematopoiesis ( EMH or sometimes EH [1]) refers to hematopoiesis occurring outside of the medulla of the bone ( bone marrow ). [2] It can be physiologic or pathologic. Physiologic EMH occurs during embryonic and fetal development; during this time the main site of fetal hematopoiesis are liver and the spleen. WebDuring embryonic development, a subset of cells in the mesoderm germ layer are specified as hemato-vascular progenitor cells, which then differentiate into endothelial cells and hematopoietic stem and progenitor cells. In zebrafish, the transcription factor npas4l (cloche) is required for the specification of hemato-vascular progenitor cells.
