    Type XVII collagen coordinates proliferation in the interfollicular epidermis

    Mika Watanabe et al.
    Type XVII collagen, a transmembranous protein in basal keratinocytes, suppresses interfollicular epidermal proliferation in neonatal and aged skin, and helps rejuvenate epidermis.

    A conserved morphogenetic mechanism for epidermal ensheathment of nociceptive sensory neurites

    Nan Jiang et al.
    Epidermal cells in vertebrates and invertebrates ensheath portions of somatosensory neurons via a conserved morphogenetic mechanism, and this ensheathment regulates morphogenesis and function of Drosophila nociceptive neurons.

    Epidermal cell turnover across tight junctions based on Kelvin's tetrakaidecahedron cell shape

    Mariko Yokouchi et al.
    The three dimensional structure of epidermal cells in the stratum granulosum provides the basis for the homeostasis of the tight junction barrier during cell turnover in the skin.

    A protein phosphatase network controls the temporal and spatial dynamics of differentiation commitment in human epidermis

    Ajay Mishra et al.
    A combination of transcriptomics, proteomics and modelling identifies a network of interacting protein phosphatases that act as a biological switch to move cells from the stem cell compartment to the differentiated compartment in cultured human epidermis.

    Epithelial geometry regulates spindle orientation and progenitor fate during formation of the mammalian epidermis

    Kimberly Box et al.
    Early in mammalian epidermal development, basal epidermal progenitor cells utilize packing and three-dimensional geometry, rather than cortical polarity cues, to inform division orientation and progenitor cell fate.

    FBN-1, a fibrillin-related protein, is required for resistance of the epidermis to mechanical deformation during C. elegans embryogenesis

    Melissa Kelley et al.
    A fibrillin-related protein, FBN-1, is a key component of the apical extracellular matrix and prevents epidermal cell deformation by biomechanical forces during morphogenesis of the C. elegans embryo.

    Epidermal Growth Factor Receptor neddylation is regulated by a desmosomal-COP9 (Constitutive Photomorphogenesis 9) signalosome complex

    Nicole Ann Najor et al.
    A protein interaction screen revealed desmosomes as a scaffold for the COP9 de-neddylating complex, to promote epidermal differentiation by governing the balance of Nedd8 and Ubiquitin modifications on Epidermal Growth Factor Receptor.

    A transgenic toolkit for visualizing and perturbing microtubules reveals unexpected functions in the epidermis

    Andrew Muroyama, Terry Lechler
    The dynamics and functions of epidermal microtubules are revealed through the use of transgenic tools to image and perturb microtubule arrays.

    Assessing the danger of self-sustained HIV epidemics in heterosexuals by population based phylogenetic cluster analysis

    Teja Turk et al.
    A method to assess the risk of self-sustained HIV transmission in heterosexuals from phylogenetic and epidemiological data is developed and, when applied to the Swiss HIV epidemic, shows that this risk is negligibly small for Switzerland.

    Egr-5 is a post-mitotic regulator of planarian epidermal differentiation

    Kimberly C Tu et al.
    The dynamic homeostasis of the planarian epidermis serves as an experimental paradigm to study stem cell dynamics and post-mitotic specification of diverse functional cell fates.
