Hematopoietic stem cell transplantation - Wikipedia. Hematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood.[1][2] It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an identical twin).[1][2]It is most often performed for patients with certain cancers of the blood or bone marrow, such as multiple myeloma or leukemia.[2] In these cases, the recipient's immune system is usually destroyed with radiation or chemotherapy before the transplantation. Infection and graft- versus- host disease are major complications of allogeneic HSCT.[2]Hematopoietic stem cell transplantation remains a dangerous procedure with many possible complications; it is reserved for patients with life- threatening diseases. As survival following the procedure has increased, its use has expanded beyond cancer to autoimmune diseases[3][4] and hereditary skeletal dysplasias; notably malignant infantile osteopetrosis[5][6] and mucopolysaccharidosis.[7]Medical uses[edit]Indications[edit]Indications for stem cell transplantation are as follows: Malignant[edit]Non- malignant[edit]Many recipients of HSCTs are multiple myeloma[9] or leukemia patients[1. Candidates for HSCTs include pediatric cases where the patient has an inborn defect such as severe combined immunodeficiency or congenital neutropenia with defective stem cells, and also children or adults with aplastic anemia[1. Other conditions[1.

Ewing's sarcoma, desmoplastic small round cell tumor, chronic granulomatous disease and Hodgkin's disease. More recently non- myeloablative, "mini transplant(microtransplantation)," procedures have been developed that require smaller doses of preparative chemo and radiation. This has allowed HSCT to be conducted in the elderly and other patients who would otherwise be considered too weak to withstand a conventional treatment regimen.

Properties. The classical definition of a stem cell requires that it possesses two properties: Self-renewal: the ability to go through numerous cycles of cell.

Number of procedures[edit]In 2. Worldwide Network for Blood and Marrow Transplantation. Of these, 2. 8,9. The main indications for transplant were lymphoproliferative disorders (5.

Europe (4. 8 percent) or the Americas (3. The Worldwide Network for Blood and Marrow Transplantation reported the millionth transplant to have been undertaken in December 2.

In 2. 01. 4, according to the World Marrow Donor Association (WMDA), stem cell products provided for unrelated transplantation worldwide had increased to 2. Graft types[edit]Autologous[edit]Autologous HSCT requires the extraction (apheresis) of haematopoietic stem cells (HSC) from the patient and storage of the harvested cells in a freezer. Baptiser Un Adulte. The patient is then treated with high- dose chemotherapy with or without radiotherapy with the intention of eradicating the patient's malignant cell population at the cost of partial or complete bone marrow ablation (destruction of patient's bone marrow's ability to grow new blood cells).

The patient's own stored stem cells are then transfused into his/her bloodstream, where they replace destroyed tissue and resume the patient's normal blood cell production. Autologous transplants have the advantage of lower risk of infection during the immune- compromised portion of the treatment since the recovery of immune function is rapid. Also, the incidence of patients experiencing rejection (and graft- versus- host disease is impossible) is very rare due to the donor and recipient being the same individual. These advantages have established autologous HSCT as one of the standard second- line treatments for such diseases as lymphoma.[1.

However, for other cancers such as acute myeloid leukemia, the reduced mortality of the autogenous relative to allogeneic HSCT may be outweighed by an increased likelihood of cancer relapse and related mortality, and therefore the allogeneic treatment may be preferred for those conditions.[1. Researchers have conducted small studies using non- myeloablative hematopoietic stem cell transplantation as a possible treatment for type I (insulin dependent) diabetes in children and adults. Stroke In Young Adults Workup. Results have been promising; however, as of 2. Allogeneic[edit]Allogeneics HSCT involves two people: the (healthy) donor and the (patient) recipient.

Allogeneic HSC donors must have a tissue (HLA) type that matches the recipient. Matching is performed on the basis of variability at three or more loci of the HLA gene, and a perfect match at these loci is preferred. Even if there is a good match at these critical alleles, the recipient will require immunosuppressive medications to mitigate graft- versus- host disease.
