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 ...
Hematopoietic stem cells (HSCs) are the stem cells [1] that give rise to other blood cells.This process is called haematopoiesis. [2] In vertebrates, the first definitive HSCs arise from the ventral endothelial wall of the embryonic aorta within the (midgestational) aorta-gonad-mesonephros region, through a process known as endothelial-to-hematopoietic transition.
Haematopoiesis (from Greek αἷμα, "blood" and ποιεῖν "to make"; also hematopoiesis in American English; sometimes also haemopoiesis or hemopoiesis) is the formation of blood cellular components. All cellular blood components are derived from haematopoietic stem cells. [3]

Granulopoiesis (or granulocytopoiesis) is a part of haematopoiesis, that leads to the production of granulocytes. A granulocyte , also referred to as a polymorphonuclear leukocyte (PMN), is a type of white blood cell that has multi lobed nuclei , usually containing three lobes, and has a significant amount of cytoplasmic granules within the ...
The pioneering work of Till and McCulloch in 1961 experimentally confirmed the development of blood cells from a single precursor hematopoietic stem cell (HSC), creating the framework for the field of hematopoiesis to be studied over the following decades. [7]
Diagram showing the development of different blood cells from hematopoietic stem cells to mature cells.. A blood cell (also called a hematopoietic cell, hemocyte, or hematocyte) is a cell produced through hematopoiesis and found mainly in the blood.
Definitive haematopoiesis is the second wave of embryonic haematopoiesis and give rise to all hematopoietic stem cells in the adult hematopoietic system. The aorta gonad mesonephros region has been shown to harbour multipotent hematopoietic colony-forming unit-spleen ( CFU -S) progenitor cells [ 1 ] and pluripotential long-term repopulating ...
