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 ...

This diagram shows the hematopoiesis as it occurs in humans. It may look incomplete when rendered directly from WikiMedia. Reference list is found at: File:Hematopoiesis (human) diagram.png. The morphological characteristics of the hematopoietic cells are shown as seen in a Wright’s stain, May-Giemsa stain or May-Grünwald-Giemsa stain.

In adults, red marrow is found mainly in the central skeleton, such as the pelvis, sternum, cranium, ribs, vertebrae and scapulae, and variably found in the proximal epiphyseal ends of long bones such as the femur and humerus. In circumstances of chronic hypoxia, the body can convert yellow marrow back to red marrow to increase blood cell ...
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.
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 ...
