    Differentiating Drosophila female germ cells initiate Polycomb silencing by regulating PRC2-interacting proteins

    Steven Z DeLuca et al.
    Characterization of Drosophila female germ cell differentiation shows that nurse cells initiate Polycomb silencing by regulating Pcl and Scm levels to alter the biochemical properties of the PRC2 H3K27 methylase.

    Dendritic spikes in hippocampal granule cells are necessary for long-term potentiation at the perforant path synapse

    Sooyun Kim et al.
    A novel mechanism of local plasticity in the distal dendrites of hippocampal granule cells.

    High-resolution transcriptional and morphogenetic profiling of cells from micropatterned human ESC gastruloid cultures

    Kyaw Thu Minn et al.
    Micropatterned differentiation of human ESCs generates gastrulation cell types – germ layers, extraembryonic, and primordial germ cells with primate characteristics – that show conserved sorting behaviors when dissociated and reseeded as single-cell mixture.

    Stem cell niche exit in C. elegans via orientation and segregation of daughter cells by a cryptic cell outside the niche

    Kacy L Gordon et al.
    A previously undetected dynamic cell structure orients the mitotic spindle of germ stem cells and grows over one daughter cell, thus helping to balance niche retention with niche exit.

    Embryonic attenuated Wnt/β-catenin signaling defines niche location and long-term stem cell fate in hair follicle

    Zijian Xu et al.
    Long-term hair follicle stem cells arise by embryonic progenitor cells occupying a niche location that is defined by attenuated Wnt/β-catenin signal.

    Long-term antigen exposure irreversibly modifies metabolic requirements for T cell function

    Marie Bettonville et al.
    Long-term exposure to recipient's alloantigens promotes major metabolic defects in T cells that are independent of PD-1-mediated regulation.

    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.

    Persistent Mycobacterium tuberculosis infection in mice requires PerM for successful cell division

    Ruojun Wang et al.
    PerM-mediated FtsB stabilization is essential for cell division of Mycobacterium tuberculosis during chronic but not acute mouse infections.

    Distinct mechanisms define murine B cell lineage immunoglobulin heavy chain (IgH) repertoires

    Yang Yang et al.
    The B-1a cell heavy chain antibody repertoire differs dramatically from the follicular and marginal zone B cell repertoire and is defined by distinct mechanisms driven by self antigens rather than antigens derived from the microbiota.

    The genome of the Hi5 germ cell line from Trichoplusia ni, an agricultural pest and novel model for small RNA biology

    Yu Fu et al.
    The genome sequence of Trichoplusia ni enables the use of this widespread lepidopteran pest as a model for both the study of small RNA pathways and insecticide resistance.
