Hemocytoblast
Hemocytoblast
Hemocytoblast (pronunciation: he·mo·cyto·blast, /ˌhēmōˈsīdōˌblast/) is a stem cell in the bone marrow that gives rise to all types of blood cells.
Etymology
The term "hemocytoblast" is derived from the Greek words "haima" meaning "blood", "kytos" meaning "cell", and "blastos" meaning "germ".
Definition
A hemocytoblast is a multipotent, hematopoietic stem cell that can differentiate into any of the blood cells including erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets).
Function
The primary function of hemocytoblasts is to maintain the constant production of blood cells throughout the lifespan of an organism. They are capable of self-renewal and differentiation into various types of blood cells depending on the body's needs.
