(A) Representative fluorescence micrographs of p-MLC in HTM cells cultured atop ECM hydrogels subjected to vehicle control, dexamethasone (D; 100 nM), simvastatin (S; 10 μM), dexamethasone + simvastatin, and dexamethasone + simvastatin + mevalonate-5-phosphate (M; 500 μM) at 3 d. Scale bar, 20 μm. (B) Analysis of p-MLC fluorescence intensity (N = 29-33 images from 3 HTM cell strains with 3 experimental replicates per cell strain). Symbols with different colors represent different cell strains; dotted line indicates control baseline. The bars and error bars indicate Mean ± SD. Significance was determined by two-way ANOVA using multiple comparisons test; shared significance indicator letters = non-significant difference (p>0.05), distinct letters = significant difference (p<0.05).
