Frog (Xenopus), as well as other amphibian, gastrulation serves as an excellent example of the role of convergent extension in embryogenesis. (wikipedia.org)
Loss of Fry function drastically affects the movement and morphological polarization of cells during gastrulation and disrupts dorsal mesodermconvergent extension, responsible for head-to-tail elongation. (nature.com)
We confirm previous results on the role of Twf1 in lamellipodia and extend those findings by linking Twf1, actin turnover, and cell polarization required for convergent extension during vertebrate gastrulation. (biorxiv.org)
Disrupts1
We show that Lrp6 downregulation (by morpholino injection) or overexpression in Xenopus embryos disrupts convergent extension, a hallmark feature of Wnt/PCP components. (silverchair.com)
Planar3
Current research is shedding light on the cellular mechanisms of convergent extension and recently the planar cell polarity (PCP) pathway was implicated in regulating the cell polarity of the factors involved in convergent extension. (wikipedia.org)
Similar results with Xenopus strabismus implicate the planar cell polarity (PCP) signaling cascade in neural convergent extension and tube closure. (silverchair.com)

Xenopus1
In Xenopus , Dishevelled (Xdsh) signaling is required for both neural tube closure and neural convergent extension, but the connection between these two morphogenetic processes remains unclear. (silverchair.com)
Midline2
We suggest that the inherent movement of the neural folds can accomplish only a finite amount of medial progress and that convergent extension of the midline is necessary to reduce the distance between the nascent neural folds, allowing them to meet and fuse. (silverchair.com)
In comparison midline convergent extension fails in dual mutants completely. (pkc-inhibitor.com)
Embryos1
The team noted that the expression of the CagA oncoprotein in X. laevis embryos led to impairment of convergent extension movements-cell movements observed during embryonic development that are involved in shaping or elongating organismal tissues and organs. (medicalxpress.com)
Blastopore3
Convergence and extension of these tissues squeezes the blastopore shut and simultaneously elongate the body axis. (wikipedia.org)
Simultaneously, on the dorsal side of the embryo, axial and paraxial mesoderm tissues undergo convergent extension which elongates the anterior-posterior axis and aids blastopore closure. (nature.com)
While we have previously shown XProfilin1 regulates blastopore closure, overexpression or depletion of XProfilin2 specifically affects convergent extensionmovement independent of mesodermal specification. (xenbase.org)
Divergent2
Alpine Transform System of New … Transform boundaries connect to perpendicular divergent (and sometimes convergent) boundaries on both ends, giving the overall appearance of zig-zags or staircases. (hourofscampering.com)
This paper concludes the two sides often face tensions and in some cases take divergent, rather than convergent, trajectories. (lu.se)
Pathways2
In addition to the non-canonical Wnt and PCP pathways involvement in convergent extension, the down-regulation of certain cell-cell adhesion molecules, such as C-cadherin and fibronectin/integrin interactions, may also play a role. (wikipedia.org)
2017. PCP and SAX-3/Robo pathways cooperate to regulate convergent extension-based nerve cord assembly in C. elegans. (ohri.ca)
Vertebrate1
Together, these data demonstrate that PCP-mediated convergent extension movements are crucial to proper vertebrate neurulation. (silverchair.com)
Elongation1
2003 Craniorachischisis in these mutants continues to be attributed to problems in convergent expansion (CE) a morphogenetic procedure leading to mediolateral narrowing and anterior-posterior elongation through mediolateral intercalation (Keller 2002 Additional areas of CE such as for example narrowing from the somites are just mildly affected in mouse solitary PCP mutants such as for example dual mutants (Music et al. (pkc-inhibitor.com)
Neural2
Should convergent extension be interrupted or incomplete, the resulting organism will have a short anteroposterior axis, wide notochord, and broad, open neural tube. (wikipedia.org)
Using disruption of Xdsh signaling, we demonstrate that convergent extension is crucial to tube closure. (silverchair.com)
Mutants1
Culture adaptation of malaria parasites selects for convergent loss-of-function mutants. (cdc.gov)
Axis1
Convergent extension (CE), sometimes called convergence and extension (C&E), is the process by which the tissue of an embryo is restructured to converge (narrow) along one axis and extend (elongate) along a perpendicular axis by cellular movement. (wikipedia.org)
Convergence2
I then presented the concept of convergence and how the UI components provided by the Ubuntu SDK can be best utilised to create great convergent apps, including some livecoding. (ubuntu.com)

Development1
Convergent extension has been primarily studied in frogs and fish due to their large embryo size and their development outside of a maternal host (in egg clutches in the water, as opposed to in a uterus). (wikipedia.org)
Cell2
Reduction of the activity of these cell-cell adhesion molecules allows for cells undergoing convergent extension to move more freely. (wikipedia.org)
Consistent with a role for a reduction of cell-cell adhesion in convergent extension, when cell-cell adhesion is not reduced, convergent extension cannot occur. (wikipedia.org)
