(a) Graphical representation of the viscosity of the PBS absent chitosan hydrogel (CHPA) and the chitosan hydrogel immersed into PBS (CHP) at 37°C as a function of time. (b) Illustrative scanning electron micrographs of chitosan hydrogel and (c) chitosan hydrogel seeded with SCAPs. Observe the rounded shape of the cells forming clusters of diverse sizes on top of the hydrogel beams (arrows).
