MYH6 and MYH7 mRNA base means in replated (35 + 2 d) vs. non-replated control (37 d) hESC-CMs derived from RNA-Seq. Base means, log2 fold change (log2(FC)), and adjusted P value (P-adj) from n = 3 culture dishes from three differentiations. Normalization and differential expression analysis was performed with DESeq2.
