pluripotency Differentiation of pluripotent stem cells Metabolic control of cell state Conclusions and perspectives Chromatin regulation and dynamics in stem cells Chromatin compaction, structure, and function Nucleosomes are formed from DNA interacting with an octamer of four histone proteins Chromatin structure balances DNA compaction and accessibility Chromatin dynamics regulate gene expression ATP-dependent nucleosome remodeling complexes establish and maintain chromatin state SWI/SNF family nucleosome remodeling factors INO80 family nucleosome remodeling factors ISWI family nucleosome remodeling factors CHD family nucleosome remodeling factors Summary Histone modifications provide an additional layer of gene regulation Histone acetylation and deacetylation Histone methylation and demethylation Polycomb group proteins mediate H3K27me3 and silencing of developmental genes Histone chaperones and histone variants regulate chromatin structure Histone H2A variants H2A.Z is a histone variant associated with active transcription H2A.X is a marker of DNA double-strand breaks macroH2A is associated with repression and heterochromatin Histone H3 variants H3.3 marks regulatory, repetitive, and actively transcribed regions CENP-A is a centromere-specific variant of histone H3 Histone chaperones FACT facilitates H2A/H2B dimer exchange to promote nucleosome-templated activities CAF1 and ASF1 promote incorporation of H3 and H4 onto newly synthesized DNA HIRA deposits H3.3 at actively transcribed and regulatory regions of chromatin ATRX/DAXX deposit H3.3 at telomeres and pericentric heterochromatin The NAP1 family import newly translated histones from the cytoplasm to the nucleus INO80 family members possess both nucleosome remodeling and histone chaperone activities Chromatin structure is dynamic and highly regulated Stem cell chromatin is dynamic and tuned to regulate cell fate ES cells carefully regulate their chromatin via specialized transcription factors Master regulators of pluripotency Pioneer transcription factors Embryonic stem cell chromatin is poised for action Histone modifications are specifically regulated in stem cells to maintain pluripotency and facilitate differentiation H3K56ac regulates pluripotency factors and developmental regulators Bivalent promoters mark lowly expressed but poised genes in ES cells Chromatin state is precisely regulated by nucleosome remodeling factors in ES cells esBAF maintains stem cell pluripotency by preserving chromatin state CHD proteins are regulators of ES cell pluripotency MBD3/NuRD generally represses expression of differentiation genes The ISWI remodeler ATPase SNF2H is essential during development INO80 remodelers repress transcription of differentiation-associated genes Polycomb group proteins silence developmental genes in ES cells Variants of H2A and H3 have specialized roles in pluripotent cells Long-range chromatin interactions are critical for regulation of pluripotency ES cells regulate chromatin by common processes to preserve pluripotency Acknowledgments References Role of lncRNAs in stem cell maintenance and differentiation Introduction Origin of
