This includes: Autologous stem cell transplants are also used for other conditions, like: Another type of transplant uses cells from a healthy donor (allogeneic stem cell transplant). Adult stem cells are also more likely to contain abnormalities due to environmental hazards, such as toxins, or from errors acquired by the cells during replication. Depending on the treatment this might be one day or two weeks. Stem cells. Stem cells are taken from one of two areas in the patients body: bone marrow or adipose (fat) tissue in their upper thigh/abdomen, however advanced stem cell procedures using MSCs derive the stem cells from bone marrow most often. Recent progress in the treatment of diseases like Parkinsons, Huntingtons, Alzheimers and stroke recovery show that transplanted adult stem cells can be used to form new brain cells, neurons and synapses following cognitive degeneration or brain injuries. Research suggests that stem cells taken from adult bone marrow have the ability to differentiate into those needed to repair the heart and blood vessels, thanks to the secretion of multiple growth factors. . And, after about three years, the stem cell transplants had a 6 percent failure rate compared with a failure rate of 60 percent in the control (drug treatment) group.
