Local cell interactions and self-amplifying individual cell ingression drive amniote gastrulation

open access: yeseLife, 2014
Gastrulation generates three layers of cells (ectoderm, mesoderm, endoderm) from a single sheet, while large scale cell movements occur across the entire embryo.

MOVEMENT OF A SESSILE CELL COLONY

open access: yesMathematical Proceedings of the Royal Irish Academy, 2012
Summary: Surface motion of an isolated sessile bacterial colony is described by a free surface condition known as the kinematic boundary condition. When the colony is attached to a surface which does not allow slip, a difficulty arises in describing the motion of the contact line at the boundary of the colony.

Modelling cell movement, cell differentiation, cell sorting and proportion regulation in Dictyostelium discoideum aggregations [PDF]

open access: yes, 2015
Understanding the mechanisms that control tissue morphogenesis and homeostasis is a central goal not only in developmental biology but also has great relevance for our understanding of various diseases, including cancer.

Cell-to-cell movement of plastids in plants [PDF]

open access: yesProceedings of the National Academy of Sciences, 2012
Our objective was to test whether or not plastids and mitochondria, the two DNA-containing organelles, move between cells in plants. As our experimental approach, we grafted two different species of tobacco, Nicotiana tabacum and Nicotiana sylvestris ...

Patterns of cell movement within the Dictyostelium slug revealed by cell type-specific, surface labeling of living cells [PDF]

open access: yes, 1994
There are cells acattered in the rear, prespore region of the Dictyostelium slug that share many of the properties of the prestalk cells and that are therefore called anterior-like cells (ALCs).

The Birth of the Eye Vesicle: When Fate Decision Equals Morphogenesis

open access: yesFrontiers in Neuroscience, 2018
As the embryonic ectoderm is induced to form the neural plate, cells inside this epithelium acquire restricted identities that will dictate their behavior and progressive differentiation.

Cell-to-cell movement of mitochondria in plants [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
Significance We report cell-to-cell movement of mitochondria through a graft junction of two tobacco species, Nicotiana tabacum and Nicotiana sylvestris . The flowers of the N.

On the mechanical interplay between intra- and inter-synchronization during collective cell migration : a numerical investigation [PDF]

open access: yes, 2013
Collective cell migration is a fundamental process that takes place during several biological phenomena such as embryogenesis, immunity response, and tumorogenesis, but the mechanisms that regulate it are still unclear.

A gradient method for the quantitative analysis of cell movement and tissue flow and its application to the analysis of multicellular Dictyostelium development [PDF]

open access: yes, 1994
We describe the application of a novel image processing method, which allows quantitative analysis of cell and tissue movement in a series of digitized video images. The result is a vector velocity field showing average direction and velocity of movement

Paracrine signalling of AGR2 stimulates RhoA function in fibroblasts and modulates cell elongation and migration

open access: yesCell Adhesion & Migration, 2019
The most prominent cancer-associated fibroblasts (CAFs) in tumor stroma is known to form a protective structure to support tumor growth. Anterior gradient-2 (AGR2), a tumor secretory protein is believed to play a pivotal role during tumor ...
