Will medical miracles never cease? In early results from a clinical trial, genetically engineered T cells (a type of white blood cell) killed off leukemia cells. Two out of three patients who received this treatment have been cancer-free for over a year. T cells could be engineered to kill a range of cancers, including cancers of the breast and colon. And approximately 60 million people across the globe have chronic kidney disease, and many will need dialysis or a transplant. Breakthrough research shows that a patient’s OWN kidney cells can be gathered and reprogrammed.
