In a "proof of concept" study, scientists at Johns Hopkins Medicine say they have successfully delivered nano-size packets of genetic code called microRNAs to treat human brain tumors implanted in mice. The contents of the super-small containers were designed to target cancer stem cells, a kind of cellular "seed" that produces countless progeny and is a relentless barrier to ridding the brain of malignant cells.
