𝙂𝙧𝙖𝙣𝙪𝙡𝙤𝙥𝙤𝙞𝙚𝙨𝙞𝙨 (Immature White Blood Cells):- The process of producing granulocytes, a type of white blood cell. It occurs in the bone marrow and involves the development of granulocytes from:
Stages
1. *Myeloblast*: Immature cell
2. *Promyelocyte*: Developing cell
3. *Myelocyte*: Intermediate stage
4. *Metamyelocyte*: Nearly mature cell
5. *Band cell*: Immature granulocyte
6. *Mature granulocyte*: Neutrophil, eosinophil, or basophil
Regulation
Granulopoiesis is regulated by growth factors, such as granulocyte-colony stimulating factor (G-CSF), which stimulate the production and maturation of granulocytes.
Importance
Granulopoiesis plays a crucial role in the immune system, helping to fight infections and inflammation.
