text: covered the work of Evan Snyder, a researcher at Burnham Institute for Medical Research in La Jolla, Calif., who commented that stem cells implanted into damaged mice brains seemed to know exactly how to do their repair work. "Even the dumbest stem cell is smarter than the smartest neurobiologist," he told the publication.
  Next on the agenda for stem-cell researchers is the curious role that stem cells play inside tumors. Williams notes the research suggesting that "rogue" stem cells in cancer are the brains of the tumor's operations and that just one out of several hundred thousand cells can be responsible for the entire metastasizing impulse that makes the disease so dangerous. Researchers are working on blocking just those stem cells; this would allow patients to avoid crippling chemotherapy and radiation treatments.
