Collective cell migration, the simultaneous movement of multiple cells that are connected by cell-cell adhesion, is ubiquitous in development, tissue repair, and tumor metastasis [1, 2]. It has been hypothesized that the directionality of cell movement during collective migration emerges as a collective property [3, 4]. Here we determine how movement directionality is established in collective ...

Directional cell movement is universally required for tissue morphogenesis. Although it is known that cell/matrix interactions are essential for directional movement in heart development, the mechanisms governing these interactions require elucidation. Here we demonstrate that a novel protein/protein interaction between blood vessel epicardial substance (Bves) and N-myc downstream regulated gen...

Plasmodesma (PD) is a channel structure that spans the cell wall and provides symplastic connection between adjacent cells. Various macromolecules are known to be transported through PD in a highly regulated manner, and plant viruses utilize their movement proteins (MPs) to gate the PD to spread cell-to-cell. The mechanism by which MP modifies PD to enable intercelluar traffic remains obscure, ...

Pigment patterns of organisms have invoked strong interest from not only biologists but also, scientists in many other fields. Zebrafish is a useful model animal for studying the mechanism of pigment pattern formation. The zebrafish stripe pattern is primarily two types of pigment cells: melanophores and xanthophores. Previous studies have reported that interactions among these pigment cells ar...

Processing incoming sensory information and transforming this input into appropriate motor responses is a critical and ongoing aspect of our moment-to-moment interaction with the environment. While the neural mechanisms in the posterior parietal cortex (PPC) that support the transformation of sensory inputs into simple eye or limb movements has received a great deal of empirical attention-in pa...

During early retinal development, progenitor cells must divide repeatedly to expand the progenitor pool. During G(1) and G(2) of the cell cycle, progenitor cell nuclei migrate back-and-forth across the proliferative zone in a process termed interkinetic nuclear movement. Because division can only occur at the ventricular surface, factors that affect the speed of nuclear movement could modulate ...

objective: glut4 is a type of glucose transporter and plays a central role in whole-body metabolism of carbohydrates. the muscle is the major site of glut4 and cell line models, to explore glut4 behaviors under new therapeutic approach, such as herbal components, should be evaluated. here, c2c12 cell line is evaluated for glut4 translocation from intracellular compartment into the cell membrane...
