 Like with the AGM, the relocation of fetal liver HSCs coincides with the differentiation of functional units, in this case hepatoblasts to hepatocytes.Mice have also shown hematopoietic activity in the umbilical arteries and the allantois, in which HSCs and endothelial cells are colocalized.Hematopoiesis then moves to the bone marrow at E18 in mice and 12wpc in humans, where it will reside permanently for the remainder of the individual's lifetime.
