Figure Lengend Snippet: Fig. 2 Transcriptome analysis of differentiated hiPSCs (IMR90) toward CMs. The hiPSCs were cultured as a monolayer on matrigel-coated plates for 2 days under pluripotent conditions and on day 0 exposed to GSK3 inhibitor, CHIR (10 µM) for 24 h. After 48 h exposed to Wnt inhibitor, IWP2 (5 µM). Spontaneously beating cardiac clusters were observed from day 9 onwards. Simultaneously, cells were exposed to test substances for a single exposure of 24 h (day1). The cells were harvested for gene array analysis on day1, day4 and day14 (Fig. 1A). Medium changes were done as indicated every alternate date. A Representative phase-contrast images of control and ISO treated hiPSC at day1-, 4 -and 14day. Scale bar, 100 µm. B PCA blot of 54,675 probe sets for three timepoints during the differentiation. C PCA blot of the 500 SPS with the highest variance across the mean of the condition‐wise samples. The respective day is indicated by the shape and the respective measured compound is indicated by the color of the dot, as labels are shown next to the plots. The distribution of the data points on the x-axis is given by the PC 1 and on the y-axis by PC2. The percentages in parentheses denote the proportion of explained variance for the respective PC.

Article Snippet: The medium was then changed to basal RPMI/B-27-ins medium and cells were kept for further 24 h. At day 2, RPMI/B-27-ins mediumwith small molecule WNT inhibitor IWP2 (Tocris, United Kingdom) 5 μM was added and cells were kept for 48 h (day 2 to day4).
