Fig.1 — Fabrication of the fiber reinforced hydrogel (2.5% GelMA+0.5% HAMA) scaffolds.

A. Schematics of the design and fabrication. Immersing the electrospun fibers inside the hydrogel precursor solution (to which cells can be added), and then crosslinking via light exposure to form a cell-laden hydrogel with electrospun fibers for reinforcement [adapted from figure 1 (15)] and B. Surface SEM images of hydrogel, PGS-PCL fiber and composite scaffolds showing the integration of the hydrogel with the electrospun microfiber.

PGS; Poly (glycerol sebacate), PCL; Poly (ε-caprolactone), UV; Ultraviolet, GelMA; Methacrylated gelatin, HAMA: Methacrylated hyaluronic acid and SEM; Scanning electron microscopy.
