keeping it in cold storage (cryopreserving) until treatment is complete. This procedure—called an autotransplant or autologous bone marrow transplantation— should avoid the problems associated with introducing cells with different HLA types. There should be no risk of rejection. But it adds the risk of possibly reinfusing cancer cells that were inadvertently stored along with the marrow.
There are small numbers of cells circulating in the blood that are capable of replenishing the bone marrow just like cells from the bone marrow itself. A transplant using these cells is often called an autologous peripheral stem cell transplant.
