    Localized epigenetic silencing of a damage-activated WNT enhancer limits regeneration in mature Drosophila imaginal discs

    Robin E Harris et al.
    Localized silencing of damage-responsive enhancers can block regenerative growth while permitting those same genes to be used for normal development.

    Pattern regulation in a regenerating jellyfish

    Chiara Sinigaglia et al.
    Clytia jellyfish regenerate body shape and organs through a mechanically driven process that coordinates tissue remodeling, localized proliferation, and precursor migration and promotes Wnt signaling at a muscle-based landmark.

    Hedgehog signaling is required for endomesodermal patterning and germ cell development in the sea anemone Nematostella vectensis

    Cheng-Yi Chen et al.
    The dependence of Nematostella germ cell specification on zygotic Hedgehog pathway activity supports the hypothesis that the eumetazoan common ancestor segregated its germline by inductive signals rather than maternal determinants.

    Resegmentation is an ancestral feature of the gnathostome vertebral skeleton

    Katharine E Criswell, J Andrew Gillis
    Shared complexities of backbone segmentation between cartilaginous fishes and tetrapods originate much earlier in vertebrate evolution than previously thought.

    tec-1 kinase negatively regulates regenerative neurogenesis in planarians

    Alexander Karge et al.
    RNAi screening in planarians finds that inhibition of the TEC-family protein tyrosine kinase tec-1 increases the regeneration of neurons through enhancement of cell survival.

    Taste bud formation depends on taste nerves

    Di Fan et al.
    The sensory nerves that carry sensations from the taste buds to the brain induce the formation of the taste buds in the embryo.

    Environmental changes in oxygen tension reveal ROS-dependent neurogenesis and regeneration in the adult newt brain

    L Shahul Hameed et al.
    Control of neural stem cells by reactive oxygen species (ROS) provides a link between systemic shifts in oxygen tension and neuronal regeneration, and suggests an evolutionary driving force for the inherent ability of newts to regenerate their brain cells.

    Cystic proliferation of germline stem cells is necessary to reproductive success and normal mating behavior in medaka

    Luisa F Arias Padilla et al.
    In medaka fish, the reduction of cystic proliferation of germ stem cells declines gametogenesis, reproduction success, and male sexual behavior, with a decrease of mating vigor.

    Bichir external gills arise via heterochronic shift that accelerates hyoid arch development

    Jan Stundl et al.
    Unique heterochrony in the cranial segments in bichirs triggers the early formation of their external gills, and might be informative about developmental mechanisms facilitating increased breathing capacity.

    Transcriptional landscape of myogenesis from human pluripotent stem cells reveals a key role of TWIST1 in maintenance of skeletal muscle progenitors

    In Young Choi et al.
    Using multiple genetic reporter system in human pluripotent stem cells, a transcriptional database for human early myogenesis has been established.
