Figure Lengend Snippet: Image processing techniques and experimental timeline. (a) Representative raw and thresholded images of nuclei, actin, and α-SMA in untreated and TGF-β1-treated human cardiac fibroblasts (scale bars: 200 μm). (b) Experimental timeline for culturing cardiac fibroblasts with reduced serum and TGF-β1 treatment. (A color version of this figure is available in the online journal.)

Article Snippet: Cell culture Primary human adult cardiac fibroblasts (Lot 3131, Cell Applications Inc., San Diego, CA, USA) were thawed into a 75 cm 2 cell culture flask with fibroblast growth medium, consisting of low glucose DMEM (1 g/L glucose) supplemented with 10% v/v fetal bovine serum (FBS) (Gibco, Waltham, MA, USA) and 1% v/v penicillin-streptomycin solution (10,000 U/mL penicillin, 10,000 μg/mL streptomycin).

Figure Lengend Snippet: Quantification of cell morphology and α-SMA expression due to ECM rigidity and TGF-β1 treatment. Human cardiac fibroblasts were cultured on low, moderate, and high PDMS-coated coated coverslips with or without 2 ng/mL TGF-β1 for one, three, and five days. Cells were immunostained and cell density (a), actin coverage (b), and α-SMA/actin coverage (c) were quantified from immunostained images (n = 4, bars indicate mean ± standard error of the mean, *P < 0.05 and **P < 0.01 according to one-way ANOVA and Tukey’s test for multiple comparisons. For detailed statistical analysis, see Supplementary Tables S2 to S4). (A color version of this figure is available in the online journal.)

Figure Lengend Snippet: Relative changes in gene expression due to ECM rigidity and TGF-β1 treatment. Human cardiac fibroblasts were cultured on low, moderate, and high PDMS-coated coated coverslips with or without 2 ng/mL TGF-β1 for one, three, and five days. RT-PCR was used to quantify the relative expression of (a) ACTA2, (b) POSTN, (c) FAP, (d) FSP1, and (e) GJA1. All data were normalized to high PDMS control group on Day 1.
