In a healthy adult person, approximately 10 11 –10 12 new blood cells are produced daily in order to maintain steady state levels in the peripheral circulation. [7] [8] All blood cells are divided into three lineages. [9] Red blood cells, also called erythrocytes, are the oxygen-carrying cells. Erythrocytes are functional and are released ...
During fetal development, hematopoiesis occurs mainly in the fetal liver and in the spleen followed by localization to the bone marrow. [4] Hematopoiesis also takes place in many other tissues or organs such as the yolk sac, the aorta-gonad mesonephros (AGM) region, and lymph nodes.
Diagram showing the development of different blood cells from haematopoietic stem cell to mature cells. Haematopoiesis (/ h ɪ ˌ m æ t ə p ɔɪ ˈ iː s ɪ s, ˌ h iː m ə t oʊ-, ˌ h ɛ m ə-/; [1] [2] from Ancient Greek αἷμα (haîma) 'blood' and ποιεῖν (poieîn) 'to make'; also hematopoiesis in American English, sometimes h(a)emopoiesis) is the formation of blood cellular ...

[1] [9] [10] The clonal population may vary in size depending on the person, where it can be less than 2% of the blood or, at the other end, can sometimes grow close to 100%. [4] [9] The incidence of clonal hematopoiesis has been found to rise dramatically with age. Recent studies have demonstrated that less than 1% of the population under age ...
