FN1 and cystic fibrosis: PCL scaffolds were thensurface-functionalized with human type I collagen (C1) and fibronectin(F) by dihydroxyphenylalanine (DOPA)-mediated mussel-inspired approach(PCL/polyDOPA/C1F), in order to mimic fibrotic cardiac tissue-likeECM composition and support human CF culture.
