To identify the function of the neural crest cells, eye development was observed in two mutant fish lines (the tfap2a;foxd3 double mutant and the paf1 mutant) in which these cells were depleted. (biologists.com)
Although PFR is now the textbook view of neural crest development, a prominent paper studying mouse neural crest recently concluded firmly with a DFR interpretation. (bath.ac.uk)
Tickle and Trinkaus published their results in a paper titled "Change in the Surface Extensibility of Fundulus Deep Cells During Early Development," in the Journal of Cell Science. (mbl.edu)
In the process of conducting the experiments to test their hypotheses about the deformability of the cell surface during different stages of development, Trinkaus and Tickle made another serendipitous discovery about cell behaviour. (mbl.edu)
Dysregulation of neural crest (NC) development has been contributing to the majority of malformations. (biomedcentral.com)

Assembly of the Cardiac Intercalated Disk during Pre- and Postnatal Development of the Human Heart [3] "In cardiac muscle, the intercalated disk (ID) at the longitudinal cell-edges of cardiomyocytes provides as a macromolecular infrastructure that integrates mechanical and electrical coupling within the heart. (edu.au)
SCAR13 is caused by pathogenic variants in the GRM1 gene encoding the metabotropic receptor of glutamate type 1 (mGlur1), which is highly expressed in Purkinje cerebellar cells, where it plays a fundamental role in cerebellar development. (bvsalud.org)

The BBB also controls the exchange and movement of nutrients, hormones and other molecules into and out of the brain for proper functioning of the CNS 1 . (researchsquare.com)
The team analyzed the culture medium from groups of melanoma cells with different densities and saw that the cells were effectively breaking down the LPA molecules nearest to them. (plos.org)
6. Bray, D. Cell movements: from molecules to motility. (edu.pl)

Cells closest to the polarizing region on the posterior side of the limb would come in contact with higher concentrations of morphogen to then form a chicken digit 4, whereas the cells furthest from the polarizing region on the anterior side of the limb would experience much lower concentrations and therefore develop the chicken digit 2. (wikipedia.org)
These cells then evaginate to form the optic vesicles. (biologists.com)
Blastula cells form blebs, remain rounded in shape, and are active but do not engage in locomotion, whereas early gastrula cells transform blebs into extended lobopodia and engage in locomotion. (mbl.edu)
They noticed that when a cell is nudged to form a bleb, somehow that cell communicates to the adjacent cells to form blebs. (mbl.edu)
However, it appears that the ability of the In its simplest form, cloning is defined stem cells to transform is limited, except as the exact replication of cells. (who.int)
But in order to attract cells, a chemoattractant needs to be present in the form of a gradient so that cells can move from a region with less of the chemical to areas where it is more abundant. (plos.org)

Neural crest cells are special cells that come from areas next to the neural tube. (lozierinstitute.org)

The mechanical part of hearing is related to the normal movement of the eardrum, and the three bones in our middle ear that carry the sound vibrations to the inner ear. (menafn.com)

Ocular Origami: Bryan and colleagues discover that in the developing zebrafish eye, cell and tissue movements in the optic cup are dependent on the extracellular matrix protein nidogen provided by surrounding neural crest cells. (biologists.com)

The neural crest cells give rise to the connective tissue components, including cartilage, bone, and ligaments in the facial and oral regions. (medscape.com)

It is important to understand whether cells acting collectively behave as a simple collection of single cells or have additional properties in terms of movement, guidance, force generation or signal transduction. (biomedcentral.com)

The blood-brain barrier (BBB) is a neurovascular unit (NVU) that serves as a physical and chemical barrier against plasma components, blood cells, and pathogens for protecting the central nervous system (CNS). (researchsquare.com)
To understand the multifaced aspects of Parkinson's disease, it may be desirable to expand the complexity of these models, to include different brain regions, vasculature, immune cells as well as additional diverse organ-specific organoids such as gut and intestine. (nature.com)

Trinkaus and Tickle also studied the deformability of the cell surface of Fundulus deep cells, especially in relation to normal bleb formation, and the extent to which blebs act as organs of locomotion in the movement of deep cells (Trinkaus Archives, Box 10, Folder 23, Tickle's MBL Research Application on Fundulus, 1975). (mbl.edu)

The absence of ganglion cells causes the muscles in the bowels to lose their ability to move stool through the intestine (peristalsis). (rarediseases.org)
