Also found in: Dictionary, Thesaurus.
haematopoiesisThe growth and maturation of the blood cells and other formed blood elements in the bone marrow. Haematopoiesis normally occurs in the flat bones, such as the pelvis, breastbone and shoulder-blades, but in times of extra demand may extend to other bones or even other tissues such as the liver. All haematopoiesis, including both red and white cells, develops from a single type of stem cell.
