Scientists create nano-size packets of genetic code aimed at brain cancer ’seed‘ cells

In a ‚proof of concept‘ study, scientists 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.
