Histone H4 acetylation and the epigenetic reader Brd4 are critical regulators of pluripotency in embryonic stem cells

Background Pluripotent cells can be differentiated into many different cell types in vitro. Successful differentiation is guided in large part by epigenetic reprogramming and regulation of critical gene expression patterns. Recent genome-wide studies have identified the distribution of different histone-post-translational modifications (PTMs) in various conditions and during cellular differentiation. However, our understanding of the abundance of histone PTMs and their regulatory mechanisms still remain unknown.
