A non-viral PDGF "bio patch" can regenerate missing or damaged bone by delivering DNA in a nano-sized particle directly into cells via genes. Repairing bone fractures, fixing craniofacial defects and improving dental implants are among potential uses. The patch employs a collagen platform seeded with particles containing the genes needed for producing bone. In experiments, it new bone fully covered skull wounds in test animals and stimulated growth in human bone marrow [[stromal cell]]s.<ref>{{cite web|url=http://www.kurzweilai.net/bio-patch-can-regrow-bone-for-dental-implants-and-craniofacial-defects |title=Bio patch can regrow bone for dental implants and craniofacial defects |doi=10.1016/j.biomaterials.2013.10.021 |publisher=KurzweilAI |date=2013-11-12 |accessdate=2013-12-28}}</ref><ref>{{cite journal |vauthors=Elangovan S, D'Mello SR, Hong L, Ross RD, Allamargot C, Dawson DV, Stanford CM, Johnson GK, Sumner DR, Salem AK | title = The enhancement of bone regeneration by gene activated matrix encoding for platelet derived growth factor | journal = Biomaterials | volume = 35 | issue = 2 | pages = 737–747 | year = 2014 | pmid = 24161167 | pmc = 3855224 | doi = 10.1016/j.biomaterials.2013.10.021 }}</ref>
