WebIn human, the process of erythropoiesis starts initially in the yolk sac, then switches to the fetal liver in the second gestational month. After birth, erythropoiesis occurs in the bone marrow. In cases in which the demand for increased erythropoiesis is required, the process can occur extramedullary (in the liver and spleen). WebB-1 cells mainly originate from the fetal liver and contain B-1a and B-1b subsets. B-2 cells are derived from the bone marrow (BM) and can be further classified into follicular B (FOB) and marginal zone B (MZB) cells.
