Study Notes
Function
- Produces blood cells: red blood cells, white blood cells, and platelets
- Responsible for hematopoiesis: the process of blood cell formation and development
Structure
- Spongy, fatty tissue found in the cavities of bones
- Divided into two types:
- Red bone marrow: found in spongy bones, responsible for hematopoiesis
- Yellow bone marrow: found in compact bones, composed mostly of fat cells
Composition
- 70% of bone marrow is composed of hematopoietic stem cells and their progeny
- 30% is composed of stromal cells: fat cells, reticular cells, and osteoblasts
Stem Cells
- Hematopoietic stem cells: capable of differentiating into different blood cell types
- Mesenchymal stem cells: capable of differentiating into stromal cells
Blood Cell Production
- Erythropoiesis: production of red blood cells
- Granulopoiesis: production of white blood cells (granulocytes)
- Thrombopoiesis: production of platelets
Clinical Significance
- Bone marrow disorders: anemia, leukemia, lymphoma, and multiple myeloma
- Bone marrow transplantation: a treatment for certain blood disorders and cancers
