Haematopoiesis
Haematopoiesis
Haematopoiesis (pronounced: hee-muh-toh-poy-ee-sis) is the process by which the body produces all types of blood cells. This includes the production of red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes) from a common stem cell known as the haematopoietic stem cell (HSC).
Etymology
The term "haematopoiesis" is derived from the Greek words "haima" meaning "blood" and "poiesis" meaning "to make".
Process
Haematopoiesis occurs in the bone marrow, which is the soft, spongy tissue found in the centre of bones. The process is regulated by various growth factors and cytokines that stimulate the proliferation and differentiation of HSCs into mature blood cells.
Types of Haematopoiesis
There are two types of haematopoiesis: myeloid and lymphoid.
- Myeloid haematopoiesis involves the production of erythrocytes, platelets, monocytes, neutrophils, eosinophils, and basophils.
- Lymphoid haematopoiesis involves the production of lymphocytes, which include B cells, T cells, and natural killer cells.
