bPEI‐AuNP‐collagen hydrogels support hiPSC‐derived cardiomyocyte function. a,b) MUSCLEMOTION‐based quantitative analysis of contraction (a) and contractility (b) of engineered cardiac tissues. c) Examples of engineered tissues' speed of contraction at different days post‐fabrication. d,e) Examples of projections of confocal images of hiPSC‐derived cardiomyocyte‐laden tissue constructs at 17 days (d) and 22 days (e) post‐fabrication stained for the cardiomyocyte‐specific marker sarcomeric‐α‐actinin and/or troponin I. n = 3. Data are mean ± SD and compared based on a two‐way ANOVA and Bonferroni's multiple comparison test. ****p < 0.0001. Scale bars: yellow: 25 µm and white: 4 µm.
