Meru couples planar cell polarity with apical-basal polarity during asymmetric cell division

Polarity is a shared feature of most cells. In epithelia, apical-basal polarity often coexists, and sometimes intersects with planar cell polarity (PCP), which orients cells in the epithelial plane. From a limited set of core building blocks (e.g. the Par complexes for apical-basal polarity and the Frizzled/Dishevelled complex for PCP), a diverse array of polarized cells and tissues are generat...

The signalling receptor MCAM coordinates apical-basal polarity and planar cell polarity during morphogenesis

The apical-basal (AB) polarity and planar cell polarity (PCP) provide an animal cell population with different phenotypes during morphogenesis. However, how cells couple these two patterning systems remains unclear. Here we provide in vivo evidence that melanoma cell adhesion molecule (MCAM) coordinates AB polarity-driven lumenogenesis and c-Jun N-terminal kinase (JNK)/PCP-dependent ciliogenesi...

Rab35 GTPase couples cell division with initiation of epithelial apico-basal polarity and lumen opening.

Establishment and maintenance of apico-basal polarity in epithelial organs must be tightly coupled with cell division, but the underlying molecular mechanisms are largely unknown. Using 3D cultures of renal MDCK cells (cysts), we found that the Rab35 GTPase plays a crucial role in polarity initiation and apical lumen positioning during the first cell division of cyst development. At the molecul...

Cell division orientation and planar cell polarity pathways.

The orientation of cell division has a crucial role in early embryo body plan specification, axis determination and cell fate diversity generation, as well as in the morphogenesis of tissues and organs. In many instances, cell division orientation is regulated by the planar cell polarity (PCP) pathways: the Wnt/Frizzled non-canonical pathway or the Fat/Dachsous/Four-jointed pathway. Firstly, us...

Embryonic polarity: Protein stability in asymmetric cell division

Recent work on pattern formation in Caenorhabditis elegans has uncovered a new mechanism of asymmetric cell division: the cytoplasm is polarized by cortical proteins, and this polarization then influences the stability of other maternally expressed proteins that in turn determine early embryonic cell fates.
