Enhanced Vascularization in Hybrid PCL/Gelatin Fibrous Scaffolds with Sustained Release of VEGF

Figure 1

Structure characterization of electrospun PCL/Gel scaffolds. SEM images of PCL/Gel-1 (a), Hep-PCL/Gel-1 (b), and Hep-PCL/Gel-1 degraded in PBS for 14 days (c) and PCL/Gel-2 (d), Hep-PCL/Gel-2 (e), and Hep-PCL/Gel-2 degraded in PBS for 14 days (f) (scale bar = 20 μm). Fluorescent images of PCL/Gel-1 with red PCL fibers labled with DiI (g), and green gelatin fibers labled with DiO (h), as well as the merge one (i) (scale bar = 20 μm).
