Abstract

How control of subcellular events in single cells determines morphogenesis on the scale of the tissue is largely unresolved. The stereotyped cross-midline mitoses of progenitors in the zebrafish neural keel provide a unique experimental paradigm for defining the role and control of single-cell orientation for tissue-level morphogenesis in vivo. We show here that the coordinated orientation of individual progenitor cell division in the neural keel is the cellular determinant required for morphogenesis into a neural tube epithelium with a single straight lumen. We find that Scribble is required for oriented cell division and that its function in this process is independent of canonical apicobasal and planar polarity pathways. We identify a role for Scribble in controlling clustering of α-catenin foci in dividing progenitors. Loss of either Scrib or N-cadherin results in abnormally oriented mitoses, reduced cross-midline cell divisions, and similar neural tube defects. We propose that Scribble-dependent nascent cell-cell adhesion clusters between neuroepithelial progenitors contribute to define orientation of their cell division. Finally, our data demonstrate that while oriented mitoses of individual cells determine neural tube architecture, the tissue can in turn feed back on its constituent cells to define their polarization and cell division orientation to ensure robust tissue morphogenesis.

  • In zebrafish, most cell divisions are parallel to the epithelial sheet, but during the neural keel/rod phase, mitotic spindles rotate 90° to be perpendicular to it.

    “Most cell divisions are parallel to the epithelial sheet, but during the neural keel/rod phase, this changes (Geldmacher-Voss et al., 2003; Žigman et al., 2011). Mitotic spindles set up parallel to the epithelial sheet, but then rotate 90° to be perpendicular to it.”

  • Spindle orientation becomes randomized in scribble mutants, and bilateral positioning of daughter cells is lost.

    “Spindle orientation becomes randomized in scribble mutants, and thus bilateral positioning of daughter cells is lost (Žigman et al., 2011).”

  • Scribble is required for cortical localization of the cadherin-catenin complex, and N-cadherin knockdown phenocopies Scribble loss.

    “Instead, Scribble is required for cortical localization of the cadherin–catenin complex, and N-cadherin knockdown phenocopies Scribble loss.”

  • This spindle orientation role does not require PCP or apical PAR proteins.

    “Surprisingly, this does not require PCP or apical PAR proteins, both partners in other Scribble-mediated events.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
