Bone Marrow, Megakaryocyte, EM
Electron micrograph of megakaryocyte from bone marrow. A megakaryocyte is a large bone marrow cell with a lobulated nucleus responsible for the production of blood thrombocytes (platelets), which are necessary for normal blood clotting. Megakaryocytes normally account for 1 out of 10,000 bone marrow cells but can increase in number nearly 10 fold during the course of certain diseases. Bone marrow is the flexible tissue in the interior of bones. In humans, red blood cells are produced by cores of bone marrow in the heads of long bones in a process known as hematopoiesis. Bone marrow is also a key component of the lymphatic system, producing the lymphocytes that support the body's immune system. Magnification unknown.
