If a person experiences serious blood loss, yellow bone marrow can activate and transform into red bone marrow. In lower vertebrates a number of other tissues may also produce blood cells, including the liver and the spleen. For this reason, B cells are known as antigen-presenting cells, as they alert other cells of the immune system to the presence of an invading microbe. However, if it is not possible to find a suitable bone marrow donor among family members, healthcare professionals try to find someone with a compatible tissue type on the bone marrow donor register. Blood cells have a limited life span. The overall 3-year survival rate is 4958% for transplants from related donors or 53% if the donor is unrelated. A dose of 1 x 103 and 2 x 108 marrow mononuclear cells per kg is necessary to establish engraftment in autologous and allogeneic marrow transplants, respectively.

This allows older adults and those with other health problems to have a transplant. The entire procedure takes 12 hours. As red blood cells age, they become less active and more fragile. It requires anesthetics and is, therefore, completely painless. All lymphocytes develop in bone marrow from immature cells called stem cells. The walls of the smallest lymphatic vessels contain muscle tissue that rhythmically propels lymph through the system.

They compare proteins in the blood cells to see if they are similar to those of the recipient. A mismatch between donor and recipient tissues can lead to an immune reaction between the cells of the host and the cells of the graft. A healthcare professional then harvests the bone marrow of a matching donor which, in many cases, is a close family member and ready it for transplant.
