Figure Lengend Snippet: a Images of splinted db/db mouse wounds at day 10 post wounding. b Quantification of migrating epithelial tongues from splinted db/db mouse wounds [Error bars correspond to standard deviations from 4 biological specimens with statistical significance assessed using paired 2-way ANOVA followed by Tukey’s multiple comparison testing, * p < 0.05, ** p < 0.01, **** p < 0.0001]. c IHC staining and d quantification of CD31 + cells/mm 2 demonstrating increased number blood vessels with HβCD + EGF treatment [Error bars correspond to standard deviations from four biological specimens with statistical significance assessed using paired student t -test, **** p < 0.0001] (E-epidermis, D-dermis; scale bar = 50 µm). d ELISA demonstrating increased levels of VEGF in splinted db/db mouse wounds upon incorporation of growth factors into HβCD hydrogels [Error bars correspond to standard deviations from four biological specimens with statistical significance assessed using paired 2-way ANOVA followed by Tukey’s multiple comparison testing, * p < 0.05, ** p < 0.01, **** p < 0.0001]. (scale bar = 50 µm).

Article Snippet: For determination of growth factor release from the hydrogels, gelatin hydrogels were loaded onto 0.4 μm PET membranes within a 24 well plate, submerged in PBS, and growth factor release quantified at 0, 12, 24, 48, 96 and 120 h using respective Quantikine ELISA kits (R&D Systems, DEG00 for EGF, DBB00 for PDGF-BB, and DVE00 for VEGF).
