Gel characterization. (A–F) SEM images of 0.12wt% collagen (A,B), 0.2wt% Coll + 0.5wt% MeHA (C,D), and 0.4wt% Coll + 0.5wt% MeHA (E,F). Scale bar = 300μm (A,C,E); Scale Bar = 15μm (B,D,F). (G) Modulus data of gels obtained via AFM. All data presented as average ± SEM with n ≥ 8 scans per composition on N ≥ 2 different gels. (H–I) Fluorescent images of avian AVC scanned by AFM. Scale bar = 100μm (H) and 25μm (I). Inset in (I) highlights scanned area. (J) 3d topographical map with modulus value overlaid. (K) Representative distributions of modulus vs. scan area. Inset numbers represent median values. N = 3 embryos. * p<0.05 vs. 0.12wt% collagen; @ p<0.01 vs. 0.2wt% Coll + 0.5wt% MeHA.
