Effect of tethered IGF-1 on new protein synthesis. Increase in cardiomyocyte [3H]phenylalanine incorporation after 14 days with tethered IGF-1 coupled with streptavidin in biotinylated peptide nanofibers (b-IGF-1 + BP) compared with peptide nanofibers alone and untethered IGF-1 coupled with streptavidin with control nonbiotinylated peptide nanofibers (b-IGF-1 + P).
