Scientists find way to disrupt brain tumor stem cells
Brain tumor stem cells can resist treatment and regrow tumors, but scientists have identified a vulnerability in these cells that could lead to a new approach in battling deadly brain tumors.
Stem cells lurking in tumors can resist treatment
Scientists are eager to make use of stem cells’ extraordinary power to transform into nearly any kind of cell, but that ability also is cause for concern in cancer treatment. New research at the School of Medicine has revealed that these stem cells are present even in slow-growing, less aggressive tumors.
