Collagen gel is an effective delivery mechanism of potassium gluconate. (A) Schematic of experimental design. Collagen gels with or without potassium gluconate were placed in transwells on top of fibroblasts in differentiation medium. Positive controls have collagen gels with TGFβ1 and without potassium gluconate, while negative controls are not cultured with TGFβ1 or potassium gluconate. (B) Quantification of αSMA positive area. * (p<0.05), ** (p<0.01), *** (p<0.001) and brackets indicate significance between treatment groups as determined by one-way ANOVA with Holm-Sidak post hoc analysis (n=3 independent experiments).
