    A multi-scale model for hair follicles reveals heterogeneous domains driving rapid spatiotemporal hair growth patterning

    Qixuan Wang et al.
    Regional differences in activator and inhibitor signals alter hair cycle pace across mouse skin and produce unique fur renewal 'landscapes', with fastest renewal on the ventrum and slowest renewal on the ear pinnae.

    Lipid-mediated regulation of SKN-1/Nrf in response to germ cell absence

    Michael J Steinbaugh et al.
    Germ cell ablation delays C. elegans aging, in part, because unconsumed fat triggers activation of the detoxification factor SKN-1/Nrf, which is regulated by lipid signals and maintains lipid homeostasis.

    Stretching the skin immediately enhances perceived stiffness and gradually enhances the predictive control of grip force

    Mor Farajian et al.
    Elucidating the contribution of augmented artificial skin-stretch stimulation to the fingertips to the immediate illusion of a higher stiffness and to an increased predictive grip force control.

    Lef1 expression in fibroblasts maintains developmental potential in adult skin to regenerate wounds

    Quan M Phan et al.
    Adult wound repair can be rejuvenated to heal like young skin by activating neonatal transcription factors in fibroblasts.

    m6A RNA methylation impacts fate choices during skin morphogenesis

    Linghe Xi et al.
    METTL3-mediated m6A modification maintains proper cell lineage specification during skin epithelium morphogenesis by coupling transcription and translation of key regulatory pathways.

    Mutations in SKI in Shprintzen–Goldberg syndrome lead to attenuated TGF-β responses through SKI stabilization

    Ilaria Gori et al.
    The mechanism underlying Shprintzen–Goldberg syndrome is solved and reveals that missense mutations in the transcriptional repressor SKI abolish ligand-induced SKI degradation, which results in attenuation of TGF-β transcriptional responses.

    Pivotal role for skin transendothelial radio-resistant anti-inflammatory macrophages in tissue repair

    Olga Barreiro et al.
    A new type of skin perivascular macrophages with extramedullary origin, access to blood and exclusive anti-inflammatory reparative properties has been characterized.

    The skin microbiome facilitates adaptive tetrodotoxin production in poisonous newts

    Patric M Vaelli et al.
    Skin-associated bacteria underlie the production of a potent defensive neurotoxin in newts, impacting host physiology, molecular evolution, and predator-prey interactions in a coevolutionary arms race.

    Skin vasculature and hair follicle cross-talking associated with stem cell activation and tissue homeostasis

    Kefei Nina Li et al.
    Hair follicle epithelium and skin vasculature remodeling are coordinated during quiescence, and their cross-talking is associated with the timing of stem cell activation.

    Interplay of opposing fate choices stalls oncogenic growth in murine skin epithelium

    Madeline Sandoval et al.
    Skin epithelium can tolerate oncogene-expressing clones through a novel cellular mechanism of inter-clonal competition between renewing progenitors along the clone's edge and differentiating progenitors within the clone's core.
