Hemopoiesis

WebHematopoiesis is the process of creating new blood cells in the body. All blood cells start off as hematopoietic stem cells, and then specialize (differentiate) into myeloid cells (erythrocytes, megakaryocytes, monocytes, neutrophils, basophils, or eosinophils) or lymphoid cells (T-lymphocytes and B-lymphocytes).
