How can stem cells be used to solve a local or global problem? Stem cell transplant for Non-Hodgkin lymphoma (NHL) Non-Hodgkin lymphomas are varied blood cancers that consist of any kind of lymphoma except Hodgkin lymphomas. They can range in severity. There are 2 main forms of lymphoma, Hodgkin lymphoma and non-Hodgkin’s lymphoma. They each contain different cells, which make up the disease. The categorisation between Hodgkin and Non-Hodgkin lymphoma is made upon examining the cancerous materiel (from biopsy or sample of the tumour tissue). The type of abnormal cells identified in the sample concludes whether the lymphoma is Hodgkin disease or non-Hodgkin’s lymphoma. Stem cell transplants are often used to treat lymphoma patients who are in remission. There are 2 main types of stem cell transplants- Autologous stem cell transplant: the transplant uses blood-forming stem cells from the clients own blood or, more rarely, from the bone marrow, are removed. Then they are frozen, and stored until after treatment. Then the stored stem cells are thawed and given back to the client through a vein. The cell finds its way through the bloodstream and returns to the bone, replacing the marrow and creating new blood cells. This process is the most common type of transplant used to aid lymphoma, but it generally cannot be done if the lymphoma has spread to the bone marrow or bloodstream. This form of stem cell transplant has an estimated 70-precent survival rate and is highly effective of destroying the cancer. Donor (allogeneic) stem cell transplant: in this case, the stem cells come from someone else. This person should be a matched donor who has tissue more or less the same as the patients. This donor can be a close relative such a brother or sister or someone not related to the patient. Umbilical cords may be used. This type of transplant is often not used in
