Researcher transplants stem cells to try to save patients' legs

A Northwestern University researcher has launched the first US trial in which a purified form of subjects' own adult stem cells was transplanted into their leg muscles with severely blocked arteries to try to grow new small blood vessels and restore circulation. Severely blocked arteries in the leg can result in the breakdown of tissue, gangrene and amputation. This painful condition is called critical limb ischemia and affects 1.4 million people in the US.

   12-03-2007 · EurekAlert!
   People who undergo nonmyeloablative stem-cell transplants, or 'mini transplants,' for leukemia, lymphoma and other blood cancers have comparable outcomes regardless of whether they receive tissue-matched stem cells from a related or unrelated donor, according to new findings by researchers at Fred Hutchinson Cancer Research Center.

   African-Americans are less likely to receive potentially life-saving stem cell transplants than Caucasians, no matter whether the cells are from an anonymous donor, a relative or are self-donated, according to research being presented here at the 2007 BMT Tandem Meetings of the American Society for Blood and Marrow Transplantation and the Center for International Blood and Marrow Transplant Research.

4. Tumor-reactive T cells boosted by hematopoietic stem cell transplantation
   02-01-2007 · EurekAlert!
   Treatment for skin cancer by infusion of tumor-reactive T cells requires patients to be pre-treated with agents that transiently decrease the number of immune cells (nonmyeloablative agents). A study in mice now indicates that pre-treatment with more intense immune cell-depleting strategies (known as myeloablative strategies) and a hematopoietic stem cell transplant enables infused tumor-reactive CD8+ T cells to increase in number more than pre-treatment with nonmyeloablative agents, and this correlates with increased tumor regression.

5. A faster way to recover from chemotherapy and marrow transplant
   06-20-2007 · EurekAlert!
   Researchers at Children's Hospital Boston report finding a practical way to increase stem cells in blood, suggesting a possible treatment to help patients recover from chemotherapy or bone marrow transplant for cancer, regaining immune function more quickly. The discovery, reported in the June 21 Nature and made possible through high-volume drug screening in fish, marks the first time stem-cell production has been induced by a small-molecule drug.

6. Type of stem cell found to reside in transplanted lungs
   03-08-2007 · EurekAlert!
   A new study involving a type of stem cells from the lungs of transplant patients demonstrates for the first time that these progenitor cells reside in adult organs and are not derived from bone marrow, which leads to the possibility that the cells may be able to help with the rejection of donated organs and with various kinds of lung disease.

   Testicular cancer patients who do not respond to traditional therapy can be cured with high-dose chemotherapy and a stem cell transplant, according to an Indiana University School of Medicine study by Lawrence Einhorn, M.D.; Stephen Williams, M.D.; Rafat Abonour, M.D., and colleagues published in the July 26 issue of the New England Journal of Medicine. Although the number of relapsed testicular cancer patients in the US is small, the IU Simon Cancer Center treats a majority of them.

    UC Irvine neurobiologist Hans Keirstead and his research team today launched a project to develop stem cell lines that genetically match human patients. These lines would allow scientists to better study conditions ranging from diabetes to Parkinson's disease, and they would provide the basis for potential patient-specific stem cell treatments.
