A Illustration of porous MN scaffold fabrication using the MeHA hydrogel. Scale bar: 2 mm. Optimization of (B) 300-MeHA concentration (2, 4, 5, and 6 wt%) and (C) 48-MeHA concentration (2, 4, 6, and 8 wt%) during MN scaffold fabrication. Optimization of the crosslinking time for (D) 4 wt% 300-MeHA and (E) 6 wt% 48-MeHA during MN scaffold fabrication.
