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. On average, bone marrow constitutes 4% of the total body mass of humans; in an adult weighing 65 kilograms (143 lb), bone marrow typically accounts for approximately 2.6 kilograms (5.7 lb).
What are adult stem cells? Adult stem cells (often called somatic stem cells) are found in many organs and tissues of the body. Adult stem cells extracted from the bone marrow of patients or compatible donors are used routinely in treating diseases such as leukaemia. Umbilical cord blood, extracted from the umbilical cord and placenta when a baby is born, is a rich source of adult stem cells.
