Epigenetic control of adult stem cell function
Nature Reviews Molecular Cell Biology 17, 643 (2016). doi:10.1038/nrm.2016.76 Authors: Alexandra Avgustinova & Salvador Aznar Benitah Mammalian embryonic development is a tightly regulated process that, from a single zygote, produces a large number of cell types with hugely divergent functions. Distinct cellular differentiation programmes are facilitated by tight transcriptional and epigenetic regulation. However, the contribution of epigenetic regulation to tissue homeostasis (Source: Nature Reviews Molecular Cell Biology)

Applying CRISPR –Cas9 tools to identify and characterize transcriptional enhancers
Nature Reviews Molecular Cell Biology 17, 597 (2016). doi:10.1038/nrm.2016.79 Authors: Rui Lopes, Gozde Korkmaz & Reuven Agami The development of the CRISPR–Cas9 system triggered a revolution in the field of genome engineering. Initially, the use of this system was focused on the study of protein-coding genes but, recently, a number of CRISPR–Cas9-based tools have been developed to study non-coding transcriptional regulatory elements.

Tight junctions: from simple barriers to multifunctional molecular gates
Nature Reviews Molecular Cell Biology 17, 564 (2016). doi:10.1038/nrm.2016.80 Authors: Ceniz Zihni, Clare Mills, Karl Matter & Maria S. Balda Epithelia and endothelia separate different tissue compartments and protect multicellular organisms from the outside world. This requires the formation of tight junctions, selective gates that control paracellular diffusion of ions and solutes. Tight junctions also form the border between the apical and basolateral plasma-membrane domains (Source: Nature Reviews Molecular Cell Biology)

Coupling changes in cell shape to chromosome segregation
Nature Reviews Molecular Cell Biology 17, 511 (2016). doi:10.1038/nrm.2016.75 Authors: Nitya Ramkumar & Buzz Baum Animal cells undergo dramatic changes in shape, mechanics and polarity as they progress through the different stages of cell division. These changes begin at mitotic entry, with cell–substrate adhesion remodelling, assembly of a cortical actomyosin network and osmotic swelling, which together enable cells to adopt (Source: Nature Reviews Molecular Cell Biology)
