haematopoiesis
Noun: The biological process by which new blood cells are produced within a living organism. This continuous, vital process occurs primarily in the bone marrow and is essential for maintaining healthy blood cell levels.
The term haematopoiesis is used in formal, scientific contexts, particularly in medicine, biology, and hematology. It describes the complex, multi-stage development of all cellular components of blood from hematopoietic stem cells. * The study focused on the molecular regulation of haematopoiesis. * Diseases of the bone marrow can severely disrupt normal haematopoiesis.
- Normal Process: "Red blood cell production, a key part of haematopoiesis, is stimulated by the hormone erythropoietin."
- Medical Context: "After the chemotherapy, the patient's haematopoiesis was suppressed, requiring supportive transfusions."
- Research Context: "Understanding haematopoiesis is crucial for developing treatments for leukemia and anemia."
- Extramedullary haematopoiesis: A condition where blood cell formation occurs outside the bone marrow, such as in the liver or spleen, often in response to severe marrow disease.
- The pathologist noted evidence of extramedullary haematopoiesis in the spleen.
- Hematopoiesis (noun): The American English spelling of the same word.
- Haematopoietic (adjective): Relating to or involved in the formation of blood cells.
- Example: "Haematopoietic stem cells are the progenitors of all blood cells."
- Hemopoiesis / Haemopoiesis (noun): A less common synonym for haematopoiesis.
- Hemopoiesis / Haemopoiesis: (noun) A direct synonym.
- Blood cell formation: (noun phrase) A descriptive, non-technical term for the process.
- Sanguification: (noun) An archaic or highly technical term for blood formation.
Given its highly technical nature, haematopoiesis is not used in phrasal verbs or idioms. It is part of specialized compound terms. * Hematopoietic system: The organs and tissues involved in blood cell production. * Hematopoietic growth factors: Natural substances that control the production and differentiation of blood cells.
