The haematopoietic system (spelled hematopoietic system in American English) is the system in the body involved in the creation of the cells of blood. [1] Structure
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 ...
Those cells' differentiation (that is, lymphopoiesis) is not complete until they migrate to lymphatic organs such as the spleen and thymus for programming by antigen challenge. Thus, among leukocytes, the term myeloid is associated with the innate immune system, in contrast to lymphoid, which is associated with the adaptive immune system.
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.
A blood cell (also called a hematopoietic cell, hemocyte, or hematocyte) is a cell produced through hematopoiesis and found mainly in the blood. Major types of blood cells include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).

The Bucks improved to 3-0 by outlasting the Heat in Miami, without superstar forward Giannis Antetokounmpo. They haven’t clinched East Group B; the Pistons are 2-0, meaning the winner of the ...
Emergency granulopoiesis is a fundamental hematopoietic mechanism activated during acute infections or inflammatory conditions, leading to a swift increase in granulocyte production, especially neutrophils, in the bone marrow. This process is essential for enhancing the innate immune system's capability to confront pathogen invasions effectively.
