Additional file 1: of Transcriptional activator DOT1L putatively regulates human embryonic stem cell differentiation into the cardiac lineage

Brightfield images of HES3 hES cells during directed differentiation into cardiac lineage. Differentiation results in distinct morphological changes leading to increased compaction among the cells as differentiation proceeds from day 0 to day 20. Similar changes observed when KIND1 cells were differentiated into cardiac cells as described earlier [43]. Magnification 10×. (PDF 554 kb
