During embryogenesis, specific ectodermal cells undergo coordinated shape changes to accommodate complex morphogenetic events such as invagination of neural precursors, extension and retraction of the germband, dorsal closure and head involution.
However, the order of the coordinated shape changes is different between the species, and the shapes also show differences.
The epidermal cells of the C. elegans embryo undergo coordinated cell shape changes that result in the morphogenetic process of elongation.
To this aim, we report experimental results on the BIOGIGA database with four feature extraction approaches (contour coordinates, shape contexts, Fourier descriptors and landmarks) and three classification methods (Euclidean distance, dynamic time warping and support vector machines).
Code representations of nodes and interactions within a pathway are called participants, and contain information that is used for drawing on the VisPathwayPanel (for example, label text, coordinates, shape, color, connectivities, and so on).
Wielding the baton sometimes like a rapier before the massive sound that I had called for, and sometimes like a matador's cape, she coordinated and shaped the combined efforts of an all-star orchestra comprised of professionals from orchestras all over the country.
In addition, other problems are that the information on location of sensors is displayed by using the screen coordinate, or shape of obstacles is determined in advance.
Our analysis of several cell shape changes leads us to propose four regulatory modules associated with ratchet-like deformations that are tuned to generate diverse cell behaviors, coordinating cell shape change across a tissue.
AJs based on classical cadherin- and nectin-mediated cell cell interactions control local membrane dynamics to polarize cell morphology and motility at the single cell level and to coordinate cell shape changes and motile behaviour at the tissue level.
A failure to coordinate cell shape transformations with chromosome separation can lead to aneuploidy and contribute to cancer [1].
Since geometric morphometric techniques retain the intrinsic geometry in landmark coordinate data, shape variation along a given PC or CV axis can be displayed and visualized graphically.
