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. WitrynaHematopoiesis begins with a single type of stem cell. These stem cells, known as hemocytoblasts and are located in red bone marrow in children and adults. In a developing fetus, hemocytoblasts are also found in the liver, spleen and lymph nodes as well as bone marrow. Ultimately, through the process of hematopoiesis, …
