    Label-free three-photon imaging of intact human cerebral organoids for tracking early events in brain development and deficits in Rett syndrome

    Murat Yildirim, Chloe Delepine ... Mriganka Sur
    Label-free three-photon imaging of whole, uncleared intact organoids generated from Rett syndrome patients show shorter migration distances and slower migration speeds of mutant radially migrating neurons with more tortuous trajectories.

    Automated quantitative histology reveals vascular morphodynamics during Arabidopsis hypocotyl secondary growth

    Martial Sankar, Kaisa Nieminen ... Christian S Hardtke
    Combining high-resolution imaging with automated image segmentation and supervised machine learning achieves accurate cellular feature extraction and automated cell type recognition in a large-scale developmental process.

    Spinal neural tube formation and tail development in human embryos

    Chloe Santos, Abigail R Marshall ... Andrew J Copp
    Analysis of 108 human embryos aged 3–7 weeks reveals modes of primary and secondary neurulation, regulation of body elongation, somite formation rate, and common occurrence of a split neural tube.

    Computational modeling of cambium activity provides a regulatory framework for simulating radial plant growth

    Ivan Lebovka, Bruno Hay Mele ... Thomas Greb
    Radial plant growth produces large parts of terrestrial biomass and can be computationally simulated with the help of an instructive framework of intercellular communication loops.

    A chronic signaling TGFb zebrafish reporter identifies immune response in melanoma

    Haley R Noonan, Alexandra M Thornock ... Leonard I Zon
    An in vivo reporter of TGFb signaling in zebrafish reveals that melanoma cells undergoing chronic TGFb signaling up-regulate extracellular matrix genes, down-regulate IFN, and are preferentially phagocytosed by macrophages compared to non-TGFb responsive melanoma cells.

    Evaluation of clonal hematopoiesis and mosaic loss of Y chromosome in cardiovascular risk: An analysis in prospective studies

    Sami Fawaz, Severine Marti ... Thierry Couffinhal
    If CHIP and mLOY do not significantly contribute to inflammation, atherosclerosis or myocardial infarction risk independently, CHIP may increase the risk of MI in men who do not carry mLOY.

    On demand expression control of endogenous genes with DExCon, DExogron and LUXon reveals differential dynamics of Rab11 family members

    Jakub Gemperle, Thomas S Harrison ... Patrick T Caswell
    DExCon, LUXon, and DExogron approaches simultaneously block endogenous gene expression and permit tuning of re-expression levels in time and space; proof-of-principle reveals unforeseen differences in protein kinetics, cargo handling, and cell migration regulation between closely related Rab11 family members.

    An improved fluorescent noncanonical amino acid for measuring conformational distributions using time-resolved transition metal ion FRET

    William N Zagotta, Brandon S Sim ... Sharona E Gordon
    Time-resolved transition metal ion fluorescence resonance energy transfer using a fluorescent, noncanonical amino acid donor and metal ion acceptor measures distances and distance distributions in proteins, allowing the equilibrium distributions among conformational states to be accurately determined.

    Identifying the immune interactions underlying HLA class I disease associations

    Bisrat J Debebe, Lies Boelen ... Becca Asquith
    HLA class I-disease associations have been studied for decades; a new approach for investigating the underlying mechanism can overcome past problems with interpretation and help to understand the etiology of human diseases.
