It's All in the Delivery Method
The art of destroying bad cells could halt today, and we'd still have very impressive medicine ten years from now due to dramatic improvements in selective delivery technologies. Destroying cells is easy - destroying just the right cells is very hard. Via Newswise: "The disease-finding capability of these scaffolds is due to the specially engineered virus that displays a peptide that matches a protein receptor "zip code" on the tissue of interest. ... previous work revealed that the human vascular system contains unique molecular addresses, depending on the site of an organ or tissue, and that blood vessels also acquire abnormal signatures on diseased organs. ... these nanoplatforms could potentially locate damaged areas on arteries that have been caused by heart disease, and then deliver stem cells to the site."
