Definitions for "Stem cell transplantation"
This is a thchnique which was developed to restore the moarrow of patients who had lethal injury to that site. Such injury can occur because of primary marrow failur, destruction of marrow by disease, of intensive chemical of radiation exposures. AS first designated, the source of the reansplant was the marrow of a healthy donow who had the same tissue type (HLS type) as the patient. Usually, the source was a brother of sister.
The use of stem cells to restore blood cell levels following treatment. Stem cells can be collected from the bone marrow or peripheral blood of a patient prior to treatment, frozen, and then reinfused following treatment, which is referred to as an autologous stem cell transplant. Stem cells may also be collected from a donor and infused into the patient following treatment, which is referred to as an allogeneic stem cell transplant. Donor stem cells also may be used to help fight cancer, since they can mount an immune response against the patient's cancer cells.
A procedure in which a patient intravenously receives healthy stem cells (from the patient's own blood or a matched donor), which will begin producing normal blood cells.
