Bone marrow

Bone marrow is the tissue comprising the center of large bones. It is the place where new blood cells are produced. Bone marrow contains two types of stem cells: hemopoietic (which can produce blood cells) and stromal (which can produce fat, cartilage and bone). Stromal stem cells have the capability to differentiate into many kinds of tissues, such as nervous tissue. Hematopoietic stem cells give rise to the three classes of blood cell that are found in the circulation: leukocytes, red blood cells (erythrocytes), and platelets (thrombocytes).
