Panminerva Med. 2017 Jul. Of these genes, only 33% are conserved in 2i compared to serum, suggesting the existence of a balance between the pluripotency network and lineage specifiers, which inhibit differentiation.

Several studies reported a functional linkage between H3K9me3 and reprogramming, showing that downregulation of either histone methyltransferases (HMTs), such as Setdb1, Ehmt1, Ehmt2, Suv39H1, and Suv39H2, or heterochromatic protein 1-, an H3K9me3 reader, enhances reprogramming efficiency.

Many classes of disorders can result in increased cardiac demand or impaired cardiac function. Results from the Breathing Not Properly Multinational Study. Incomplete erasure of tissue-specific DNA methylation and aberrant de novo methylation during reprogramming partially explain the persistent expression of somatic genes in iPSCs [133, 135]. Based on this observation, Austin Smith and coworkers pioneered the use of small-molecule inhibitors to block the FGF4 pathway via MEK and GSK3 inhibition, enabling mESCs to grow in minimal, serum-free media. 2017 ACC/AHA/HFSA Focused Update of the 2013 ACCF/AHA Guideline for the Management of Heart Failure: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines and the Heart Failure Society of America. Trimethylation at H3K9me3, associated with constitutive heterochromatin and imprinted genes, is also a barrier in somatic cell reprogramming [42, 138, 139]. Soufi A., Donahue G., Zaret K. S. Facilitators and impediments of the pluripotency reprogramming factors' initial engagement with the genome. Only a small fraction of transfected cells (0.13%) become iPSCs [126], indicating that somatic cells must overcome barriers to revert to pluripotent state.
