    Retinal stem cells modulate proliferative parameters to coordinate post-embryonic morphogenesis in the eye of fish

    Erika Tsingos, Burkhard Höckendorf ... Joachim Wittbrodt
    3D niche topology imposes a spatially biased random stem cell loss, which is differentially fine-tuned in neural retina and retinal pigmented epithelium to regulate growth, shape, and cellular topology.

    YAP controls retinal stem cell DNA replication timing and genomic stability

    Pauline Cabochette, Guillermo Vega-Lopez ... Muriel Perron
    The Hippo pathway downstream effector YAP regulates S-phase progression to protect neural stem cells of the retina from experiencing genomic instability.

    Eye morphogenesis driven by epithelial flow into the optic cup facilitated by modulation of bone morphogenetic protein

    Stephan Heermann, Lucas Schütz ... Joachim Wittbrodt
    The lens-averted domains of the optic vesicle are reservoirs of neuroretinal cells that flow into the developing optic cup in a process that is critically influenced by BMP signaling.

    Regulation of canonical Wnt signalling by the ciliopathy protein MKS1 and the E2 ubiquitin-conjugating enzyme UBE2E1

    Katarzyna Szymanska, Karsten Boldt ... Colin A Johnson
    Interacting MKS1 and UBE2E1 regulate canonical Wnt signaling through modulation of beta-catenin levels at the base of primary cilium, providing new insights into ciliopathy disease mechanisms.

    Single-cell RNA sequencing unravels the transcriptional network underlying zebrafish retina regeneration

    Laura Celotto, Fabian Rost ... Michael Brand
    Single-cell transcriptome analysis of the regenerating retina in adult zebrafish reveals molecular control steps during Müller glia stem cell activation, progressive differentiation, and neural regeneration.

    Islet vascularization is regulated by primary endothelial cilia via VEGF-A-dependent signaling

    Yan Xiong, M Julia Scerbo ... Per-Olof Berggren
    Primary cilia on endothelial cells are required for VEGF-A/ VEGFR2-dependent signaling, islet vascularization and, consequently, nutrient delivery and insulin disposal.

    Lack of CCDC146, a ubiquitous centriole and microtubule-associated protein, leads to non-syndromic male infertility in human and mouse

    Jana Muroňová, Zine Eddine Kherraf ... Christophe Arnoult
    CCDC146 is a structural component of the flagellum in sperm, located in the doublet microtubules of the axoneme, whose absence leads to multiple morphological anomalies of the flagellum.

    The heteromeric PC-1/PC-2 polycystin complex is activated by the PC-1 N-terminus

    Kotdaji Ha, Mai Nobuhara ... Markus Delling
    Soluble fragments cleaved from the N-terminus of PC-1 activate the PC-1/PC-2 heteromeric polycystin channel, describing for the first time that the N-terminus itself is an endogenous ligand.

    Ciliary transcription factors and miRNAs precisely regulate Cp110 levels required for ciliary adhesions and ciliogenesis

    Peter Walentek, Ian K Quigley ... Richard M Harland
    At optimal concentrations, the ciliary inhibitor Cp110 promotes ciliogenesis by localization to previously uncharacterized sites at the basal body, where it recruits ciliary adhesion complexes that mediate basal body interaction with F-actin networks.

    Fluid extraction from the left-right organizer uncovers mechanical properties needed for symmetry breaking

    Pedro Sampaio, Sara Pestana ... Susana Santos Lopes
    Zebrafish have a physiological time-window of 1 hr for breaking left-right symmetry and are highly sensitive to the left-right organizer anterior fluid mechanics rather than to the nature of its fluid content.
