Plasticity of both planar cell polarity and cell identity during the development of Drosophila

open access: yeseLife, 2014
Drosophila has helped us understand the genetic mechanisms of pattern formation. Particularly useful have been those organs in which different cell identities and polarities are displayed cell by cell in the cuticle and epidermis (Lawrence, 1992 ...

May the force be with you

open access: yeseLife, 2018
Understanding the coordination of the forces generated in embryos by two processes, convergent extension and convergent thickening, is key to understanding how a hollow sphere of cells develops into an elongated embryo.

A QUESTIONNAIRE TO DETERMINE THE WORK MOTIVATION OF AGRICULTURAL EXTENSION WORKERS IN INDONESIA

open access: yesAGRISE, 2022
A review of the literature reveals that most previous studies only used achievement motivation theory to assess the work motivation of agricultural extension workers in Indonesia.

A geometric-tension-dynamics model of epithelial convergent extension. [PDF]

open access: yesProc Natl Acad Sci U S A
Convergent extension of epithelial tissue is a key motif of animal morphogenesis. On a coarse scale, cell motion resembles laminar fluid flow; yet in contrast to a fluid, epithelial cells adhere to each other and maintain the tissue layer under actively generated internal tension.

Model of Convergent Extension in Animal Morphogenesis [PDF]

open access: yesPhysical Review Letters, 2000
We argue that energy minimization can explain the pattern of cell movements in the morphogenetic process known as convergent extension provided that the cell-cell adhesive energy has a certain type of anisotropy, which we describe. This single simple property suffices to cause the cell elongation, cell alignment, and lengthening of a cellular array ...

Large, long range tensile forces drive convergence during Xenopus blastopore closure and body axis elongation

open access: yeseLife, 2018
Indirect evidence suggests that blastopore closure during gastrulation of anamniotes, including amphibians such as Xenopus laevis, depends on circumblastoporal convergence forces generated by the marginal zone (MZ), but direct evidence is lacking.

On Deferred Statistical Convergence of Sequences in Neutrosophic Normed Spaces [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2022
In this paper, we introduce the notion of deferred statistical convergence in the neutrosophic normed spaces as an extension of statistical convergence, $\lambda$-statistical convergence, and lacunary statistical convergence.

Functional conservation of Nematostella Wnts in canonical and noncanonical Wnt-signaling

open access: yesBiology Open, 2011
Summary Cnidarians surprise by the completeness of Wnt gene subfamilies (11) expressed in an overlapping pattern along the anterior-posterior axis. While the functional conservation of canonical Wnt-signaling components in cnidarian gastrulation and ...

Update on the Role of the Non-Canonical Wnt/Planar Cell Polarity Pathway in Neural Tube Defects

open access: yesCells, 2019
Neural tube defects (NTDs), including spina bifida and anencephaly, represent the most severe and common malformations of the central nervous system affecting 0.7−3 per 1000 live births.

The distribution of Dishevelled in convergently extending mesoderm [PDF]

open access: yes, 2013
Convergent extension (CE) is a conserved morphogenetic movement that drives axial lengthening of the primary body axis and depends on the planar cell polarity (PCP) pathway.
