Bone Marrow

Meaning

Bone marrow is the flexible, spongy tissue found inside the central cavities of large bones, serving as the primary site for hematopoiesis, the production of all blood cells. This vital tissue houses hematopoietic stem cells responsible for generating erythrocytes, leukocytes, and platelets. Furthermore, it contains mesenchymal stem cells which are crucial precursors for bone, cartilage, and fat cells, underscoring its role in tissue maintenance and repair.
