A Radial Actin Network in Apical Constriction [PDF]
Developmental Cell, 2016 Contractile actomyosin networks are central to cell shape change, rearrangements, and migration during animal tissue morphogenesis. In this issue of Developmental Cell, Coravos and Martin (2016) report that the actin network is radially polarized in apically constricting cells, suggesting a constriction model similar to the contraction mechanism in ...

Accuracy of Root ZXII, E-PEX and FIND apex locators in teeth with vital pulp: an in vivo study
Brazilian Oral Research, 2021 : This research evaluated, in vivo, the accuracy of three electronic apex locators - EALs (Root ZXII, E-PEX and FIND) in teeth with vital pulp submitted to biopulpectomy, preserving the periodontal stump.

Sonic hedgehog signaling directs patterned cell remodeling during cranial neural tube closure
eLife, 2020 Neural tube closure defects are a major cause of infant mortality, with exencephaly accounting for nearly one-third of cases. However, the mechanisms of cranial neural tube closure are not well understood.

Rho kinase-dependent apical constriction counteracts M-phase apical expansion to enable mouse neural tube closure. [PDF]
J Cell Sci, 2019 Cellular generation of mechanical forces required to close the presumptive spinal neural tube, the "posterior neuropore" (PNP), involves interkinetic nuclear migration (INM) and apical constriction. Both processes change neuroepithelial apical dimensions,

A dynamic microtubule cytoskeleton directs medial actomyosin function during tube formation [PDF]
, 2014 The cytoskeleton is a major determinant of cell-shape changes that drive the formation of complex tissues during development. Important roles for actomyosin during tissue morphogenesis have been identified, but the role of the microtubule cytoskeleton is

Effect of apical constriction on MF speed and cell packing.
, 2022 A) The MF speed decreases as apical constriction increases. B) The cellular mosaic becomes increasingly packed with increasing apical constriction. This speed dependence on apical constriction is a consequence of the signaling differential equations ...

DRhoGEF2 regulates cellular tension and cell pulsations in the Amnioserosa during Drosophila dorsal closure. [PDF]
PLoS ONE, 2011 Coordination of apical constriction in epithelial sheets is a fundamental process during embryogenesis. Here, we show that DRhoGEF2 is a key regulator of apical pulsation and constriction of amnioserosal cells during Drosophila dorsal closure ...
