a,b, Quantification of ADSCs (a) and CFs (b) viability by CCK-8 assay on days 1, day 3 and day 7; n = 6 independent experiments per group. c, SEM images showing CF attachment to and retention on the interconnected microchannels of the PCL/gelatin (3:1) PHMs; n = 4 independent experiments. Arrow indicates CFs. d, 3D image of CFs on the surface of the PHMs by live/dead staining 7 days after cell seeding, n = 6 independent experiments per group. The data are expressed as mean ± s.d. *p<0.05 and ***p<0.001. Data were analysed by one-way ANOVA followed by Bonferroni’s post hoc test. CFs: cardiac fibroblasts; ADSCs: adipose-derived stem cells.
