The fight against cancer has taken another promising step forward as researchers at Harvard Medical School have found that stem cells can be programmed to attack brain cancer cells. It was discovered that genetically engineered stem cells produce and secrete toxins which kill brain tumors, without killing normal cells or themselves. The key to this treatment is that the stem cells release cancer cell killing toxins, but the toxins produced do not kill the stem cells or normal cells. Dr Khalid Shah, lead author and director of the molecular neurotherapy and imaging lab at Massachusetts General Hospital and Harvard Medical School, said the results were very positive; he hopes that clinical trials will be in place in the next five years.
