Hematopoiesis ensures you have a healthy supply of blood cells to supply oxygen to your tissue (red blood cells), fight infection (white blood cells) and clot your blood when you’re injured (platelets).

2017年6月12日 · Hematopoiesis is the term used to describe the differentiation of blood cells from hematopoietic stem cells. This process is continually required to maintain the levels of circulating blood cells in the body.

2017年9月27日 · Hematopoiesis is the production of all of the cellular components of blood and blood plasma. It occurs within the hematopoietic system, which includes organs and tissues...

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 components.

In the embryo and fetus it takes place in a variety of sites including the liver, spleen, thymus, lymph nodes, and bone marrow; from birth throughout the rest of life it is mainly in the bone marrow with a small amount occurring in lymph nodes. Called also hematogenesis, hemogenesis, and hemopoiesis.

2023年5月1日 · Hematopoiesis is the process of creating a wide variety of blood and bone marrow cells, namely erythrocytes, platelets, granulocytes, lymphocytes, and monocytes. This process begins with multipotent hematopoietic stem cells (HSC) which have the capability of dividing into either a multipotent progenitor cell or to self-renew.

2023年11月9日 · The process by which these cells develop throughout extra-uterine life is known as haematopoiesis; the Greek translation of which simply means “to make blood”. The bone marrow is comprised of a myriad of haematopoietic stem cells that respond to a variety of biochemical cues that promote their differentiation of mature blood cells.

2022年5月18日 · All blood cells are produced by a mechanism known as hematopoiesis, arising from a single cell type known as a hematopoietic stem cell (HSC). Stem cells are cells that differentiate into other cell types; they are self-renewing …

2024年4月10日 · Hematopoiesis, the process of blood cell production, is regulated to maintain a steady and constant supply of mature blood cells while balancing cell loss due to aging. Red blood cells (erythrocytes) have an average lifespan of 120 days before being phagocytosed and digested by spleen macrophages.

Hematopoiesis (hemato–, blood; –poiesis, making) is the formation of the formed elements of the blood. All blood cells begin as pluripotent stem cells in the red bone marrow. These stem cells can be influenced by the body to differentiate into any of the mature blood cells.
