Representative fluorescence images of LIVE/DEAD®-stained HUVECs on the a gelatin-coated coverslips, b pristine PCL, c PCL-NH2, d PCL-gelatin, e PCL-g-P(GMA)1 from 1 h of ATRP, f PCL-g-P(GMA)2 from 3 h of ATRP, g PCL-g-P(GMA)1-c-gelatin, and h PCL-g-P(GMA)2-c-gelatin surfaces. Rapid endothelialization was observed on all the gelatinized PCL surfaces. Scale bar 20 μm
