Selected gene sets enriched in hESC-CMs relative to hESCs.

CSSCMP score and PVal were calculated based on seven data sets. For comparison, GSEA results in four studies are shown: study S1:purified hESC-CM (14 days) [3], S2: hESC-CM cluster (21 days) [5], S3: hESC-CM cluster (49 days) [5], and S4: purified hESC-derived ventricular (21 days) [7]. The ’1’s under the four studies mean that the corresponding gene sets are enriched, while ’0’s mean not enriched. Details can be found in the supplementary files.
