    University of Iowa researchers have successfully developed a way to regrow bone within a living body using DNA.

    University of Iowa researchers have developed a collagen scaffold capable of growing bone from within a living body.  Past attempts at re-growing bone have been costly and unsuccessful for the most part.  The new method works better because it delivers DNA to the cells, so that the cells produce the protein instead of just delivering the protein alone.  In experiments, the team was able to regrow enough bone to cover skull wounds in test animals.  Successful bone regeneration techniques would have major implications for treating musculoskeletal problems or birth defects.
