During the autologous transplantation of stems cells from bone marrow to produce new blood cells why all the other stem cells other than the one obtained are destroyed?
Autologous stem cell transplants are used to treat individuals who have had their bone marrow destroyed or damaged by diseases such as lymphomas or by irradiation or cancer treatments. As they are damaged and potentially cancerous, they are removed. They are then replaced in the transplant. The whole idea is to destroy all the cells before transplanting the marrow back.
