• Use of stem cells as an adjunct in the treatment of numerous types of cancer, including brain tumors, ovarian cancer, various solid tumors, multiple myeloma, breast cancer, and non-Hodgkin's lymphoma.

• The adult stem cells are purified from bone marrow or circulating blood, preferably from the patient, and, after treatment to destroy the cancer cells, the patient is given back their own purified stem cells.

• Adult stem cells have also been used successfully to treat several autoimmune diseases such as multiple sclerosis, systemic lupus, juvenile rheumatoid arthritis, and rheumatoid arthritis, as well as anemias.

• Prentice cited an August report that indicated that the bone marrow stem cells could be changed into neurons that proliferate in cell culture

• Scientists from Duke University Medical Center in the US used a cocktail of steroids and growth factors to retrain cells that would normally form fat tissue into another type of cell known as a chondrocyte, or cartilage cell.
