Mechanical roles of apical constriction, cell elongation, and cell migration during neural tube formation in Xenopus
Neural tube closure is an important and necessary process during the development of the central nervous system. The formation of the neural tube structure from a flat sheet of neural epithelium requires several cell morphogenetic events and tissue dynamics to account for the mechanics of tissue deformation. Cell elongation changes cuboidal cells into columnar cells, and apical constriction then...
متن کاملFolate receptor 1 is necessary for neural plate cell apical constriction during Xenopus neural tube formation.
Folate supplementation prevents up to 70% of neural tube defects (NTDs), which result from a failure of neural tube closure during embryogenesis. The elucidation of the mechanisms underlying folate action has been challenging. This study introduces Xenopus laevis as a model to determine the cellular and molecular mechanisms involved in folate action during neural tube formation. We show that kn...

متن کاملLulu Regulates Shroom-Induced Apical Constriction during Neural Tube Closure
Apical constriction is an essential cell behavior during neural tube closure, but its underlying mechanisms are not fully understood. Lulu, or EPB4.1l5, is a FERM domain protein that has been implicated in apical constriction and actomyosin contractility in mouse embryos and cultured cells. Interference with the function of Lulu in Xenopus embryos by a specific antisense morpholino oligonucleot...
متن کاملCell-Autonomous Ca(2+) Flashes Elicit Pulsed Contractions of an Apical Actin Network to Drive Apical Constriction during Neural Tube Closure.
Neurulation is a critical period in all vertebrates and results in the formation of the neural tube, which gives rise to the CNS. Apical constriction is one of the fundamental morphogenetic movements that drives neural tube closure. Using live imaging, we show that apical constriction during the neurulation is a stepwise process driven by cell-autonomous and asynchronous contraction pulses foll...
