A patent was issued to Professor Martin Yarmush entitled, "Elastin based growth factor delivery platform for wound healing and regeneration" (Patent number 8940868). The invention is based on the development of a potent growth factor delivery system by creating a fusion polypeptide that includes two portions: a growth factor protein and an elastin-like peptide set of repeats. The chimeric protein produced is administered directly to a wound site as a nanoparticle accelerating recovery.
