Additional file 6: of Transcriptional activator DOT1L putatively regulates human embryonic stem cell differentiation into the cardiac lineage

ChIP sequencing of occupancy of H3K79me2 on DMD gene during cardiac differentiation of KIND1 and HES3 cells showing occupancy of H3K79me2 methylation mark brought about by DOT1L on DMD gene during cardiac differentiation. Results clearly show significant peaks representing the DOT1L specific methylation mark on days 12 and 20 as compared to day 0 suggestive of its activation by DOT1L during cardiac differentiation in vitro.

Characterization of cardiac differentiation of HES3 cells by immunofluorescence studies. Expression of NKX2.5 (A) and CTNT (B) on days 12 and 20 observed by immunofluorescence. (A) Distinct nuclear expression of NKX2.5 observed and (B) CTNT cell surface expression. Similar changes observed when KIND1 cells were differentiated into cardiac cells as described earlier [43]. Counterstaining using DAPI. Magnifications 20×. (PDF 450 kb

Characterization of cardiac differentiation of HES3 cells by quantitative real-time PCR (qRT-PCR). Expression of transcripts representing pluripotency (OCT4), cardiac mesoderm (MESP1), cardiac progenitors (NKX2.5, MEF2C), and cardiomyocytes (CTNT) at days 0, 12, and 20 during 20 days of cardiac differentiation. Note OCT-4 expression in undifferentiated cells is downregulated as the cells initiate differentiation. Early cardiac markers detected on day 12 and mature markers upregulated on day 20. Similar changes in transcripts expression observed when KIND1 cells were differentiated into cardiac cells as described earlier [43]. Error bars represent ÂąSEM. (PDF 410 kb

Dystrophin gene expression during cardiac differentiation of KIND1 hES cells on days 0, 12, and 20 during cardiac differentiation of KIND1 hES cell line. Expression of Dystrophin increased in cardiac progenitors and cardiomyocytes compared to undifferentiated KIND1 cells. Results in agreement with earlier reports in DOT1L conditional knockout mice heart concluding Dystrophin as a direct target of DOT1L [35]. Error bars represent ¹SEM. (PDF 329 kb

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

ChIP sequencing in KIND1 and HES3 cells during cardiac differentiation visualized by Integrated Genome Viewer shows binding profile of H3K79me2 modification across genes HNF4A, LEFTY1, NOGGIN, NQO1, OTX2, and NPTX2 in KIND1 (green) and HES3 (red) cells at days 0, 12, and 20 of cardiac differentiation.
