Transplantation of stem cells are taken from the bone marrow, peripheral blood or umbilical cord of healthy, matched donors. Hematopoietic stem cell transplantation (HSCT) involves intravenous infusion of stem cells to those who have either a damaged bone marrow or defective immune system. Transplantation is a simple process. Bone marrow product is infused through a central vein over a period of several hours. The hematopoietic cells are able to go to the bone marrow through tracking mechanisms. Patients who suffer from RD will now have more stem cells that can differentiate into immune cells.
