A bio patch that can regrow bone
Iowa City IA (SPX) Nov 11, 2013
Researchers at the University of Iowa have created a bio patch to regenerate missing or damaged bone by putting DNA into a nano-sized particle that delivers bone-producing instructions directly into cells. The bone-regeneration kit relies on a collagen platform seeded with particles containing the genes needed for producing bone. In experiments, the gene-encoding bio patch successfully regrew bone fully enough to cover skull wounds in test animals. It also stimulated new growth in human bone marro ... read more
