    Nuclear receptor NR4A is required for patterning at the ends of the planarian anterior-posterior axis

    Dayan J Li et al.
    NR4A is a broadly conserved transcription factor that is required for concordance of patterning information and anatomy at both ends of the planarian anterior-posterior axis.

    Two FGFRL-Wnt circuits organize the planarian anteroposterior axis

    M Lucila Scimone et al.
    Single-cell RNA sequencing identifies an adult regional gene expression map in planarian muscle that includes two FGFRL-Wnt circuits controlling head and trunk tissue pattern.

    Affinity and dose of TCR engagement yield proportional enhancer and gene activity in CD4+ T cells

    Karmel A Allison et al.
    Pre-existing enhancers interpret T cell signaling strength in an analogue manner to direct quantitative changes in gene expression within the context of an overall digital response.

    Cell lineage-dependent chiral actomyosin flows drive cellular rearrangements in early Caenorhabditis elegans development

    Lokesh G Pimpale et al.
    Developmentally controlled chiral counter-rotating actomyosin flows drive cell-lineage spindle skews and cell rearrangements during cytokinesis in early nematode development.

    Nodal and planar cell polarity signaling cooperate to regulate zebrafish convergence and extension gastrulation movements

    Margot LK Williams, Lilianna Solnica-Krezel
    Nodal signaling regulates gastrulation cell behaviors largely in parallel with planar cell polarity signaling and is sufficient for ex vivo extension of embryonic explants.

    The palmitoyl acyltransferase ZDHHC14 controls Kv1-family potassium channel clustering at the axon initial segment

    Shaun S Sanders et al.
    ZDHHC14 controls palmitoylation and axon initial segment targeting of PSD93 and Kv1-family potassium channels, events that are essential for normal neuronal excitability.

    Lin28a/let-7 pathway modulates the Hox code via Polycomb regulation during axial patterning in vertebrates

    Tempei Sato et al.
    Genetic analyses reveal that the loss of Lin28a causes axial shortening with mild skeletal transformations via decreased PRC1 at Hox genes, establishing a new pathway in the “Hox code.”.

    Unipolar distributions of junctional Myosin II identify cell stripe boundaries that drive cell intercalation throughout Drosophila axis extension

    Robert J Tetley et al.
    Analysing Myosin II unipolar planar polarisation with high spatial and temporal resolution during Drosophila axis extension reveals how tissue boundaries drive polarized cell intercalation while limiting cell mixing.
