Adult Bone Marrow Stem Cells Deliver Cancer Therapy Without Side Effects
HOUSTON, November 4, 2004 (LifeSiteNews.com) - Stem cells taken from bone marrow are being used to reproduce the effects of a cancer treatment called interferon beta and avoiding toxic side effects. Researchers at the University of Texas have reported in Wednesday's issue of the Journal of the National Cancer Institute that experiments with cancerous mice have had positive results killing cancer cells, without damaging surrounding tissue.
The mice which underwent the stem cell treatment lived significantly longer than those treated with the interferon alone and than those with no treatment. Mice with human breast cancer treated with the engineered human stem cells survived for 60 days. Mice treated with interferon beta alone lived for 41 days. Mice with melanoma treated with the stem cells survived 73.5 days, compared with 30 days for untreated mice
Research team member, Dr. Michael Andreeff, said the stem cells moved like guided missiles, targeting tumor cells and producing high concentrations of therapeutic proteins within the tumor cells. Andreeff, a professor at the University of Texas M.D. Anderson Cancer Center, plans to test the treatment on humans within a year.
