Web30 de jun. de 2012 · 3. Stages of Hematopoiesis Mesoblastic stage – first month of embryonic life where cells are formed outside the embryo in the mesenchyme of the yolk sac. Hepatic stage – by the 6th week Medullary stage – by the 5th month blood cell formation occurs in the bone marrow. Haematopoiesis is the formation of blood cellular components. All cellular blood components are derived from haematopoietic stem cells. In a healthy adult human, roughly ten billion (10 ) to a hundred billion (10 ) new blood cells are produced per day, in order to maintain steady state levels in the peripheral circulation.
