Prenatally, hematopoiesis occurs in the yolk sack, then in the liver, and lastly in the bone marrow. In the normal situation, hematopoiesis in adults occurs in the bone marrow and lymphatic tissues.All types of blood cells are derived from primitive cells (stem cells) that are pluripotent (they have the potential to develop into all types of blood cells).ematopoiesis: The production of all types of blood cells including formation, development, and differentiation of blood cells.
Blood cells are constantly formed through a process called hematopoiesis (also called hemopoiesis). The hematopoietic stem cells âthose that give rise to blood cellsâoriginate in the yolk sac of the human embryo and then migrate to the liver.Hematopoiesis thus occurs in the liver of the fetus.ymphoid tissue includes the lymph nodes, tonsils, spleen, and thymus. The bone marrow produces all of the different types of blood cells; the lymphoid tissue produces lymphocytes derived from cells that originated in the bone marrow. Hematopoiesis begins the same way in both myeloid and lymphoid tissue.
