...Nadia I. Manzi; Bailey N. de Jesus; Yu Shi; Daniel J. Dickinson ABSTRACT During asymmetric cell division, cell polarity is coordinated with the cell cycle to allow proper inheritance of cell fate determinants and the generation of cellular diversity. In the Caenorhabditis elegans zygote, polarity...

... through Fzd3 receptor ( Lyuksyutova et al., 2003 ; Onishi and Zou, 2017 ). This is part of the planar cell polarity (PCP) signaling, a pathway that is independent of β-catenin/Tcf/Lef proteins. In addition, guidance pathways coordinate with adhesion molecules such as N-cadherin and integrins to promote...

...Daniel B. Dranow; Pierre Le Pabic; Thomas F. Schilling ABSTRACT Non-canonical/β-catenin-independent Wnt signaling plays crucial roles in tissue/cell polarity in epithelia, but its functions have been less well studied in mesenchymal tissues, such as the skeleton. Mutations in non-canonical Wnt...

Together, our findings imply a role for FAK in controlling the timing of pancreatic lineage commitment and/or differentiation in the embryonic...

In epithelial cells, the Hippo pathway integrates diverse biological inputs, such as cell polarity and cell-cell contacts, but Drosophila blood cells lack the conspicuous polarity of epithelial cells. Here, we show that the septate-junction components Cora and NrxIV promote...

... apical-basal polarity is remodeled and turned into front-back and inside-outside as well as apical-basal polarities, during collective migration. We find that the Crumbs (Crb) complex is required for the generation of the three distinct but interconnected cell polarities of border cells. Specifically...
