VEGF immobilization and release from electrospun scaffolds. (A) Immunostaining of bound VEGF on heparin modified electrospun fibers. (B) Density of immobilized VEGF vs input VEGF concentration for the electrospun scaffolds with untreated PLLA, heparin-modified PLLA and heparin modified PLLA/5%PCL. (C) Release of VEGF over 7 days from the electrospun scaffolds with untreated PLLA, heparin-modified PLLA and heparin-modified PLLA/5%PCL. Results for untreated PLLA and PLLA/5%PCL were similar, and thus only untreated PLLA is shown.
