WebJul 7, 2024 · It has long been accepted that extra-embryonic haematopoiesis (formation of blood cells outside of the embryo) precedes intra-embryonic blood cell development. Around week two of gestation, mesodermal cells congregate within the yolk sack of the developing embryo to form well defined cell clusters. Hematopoiesis (pronounced “heh-ma-tuh-poy-EE-sus”) is blood cell production. Your body continually makes new blood cells to replace old blood cells so you have a steady blood supply. Hematopoiesis starts before birth and continues as a cycle throughout life.
