In some taxa these are immotile structures, whereas in other taxa the base of pteromorphs is de-sclerotized, forming a linear hinge, and inserted with a highly differentiated musculature, allowing for motility of this structure.
Regarding tumour cell movement, we allow for random motion of the cells and so specify, where D p is the random motility co-efficient which is assumed to be constant.
To allow for increases both in mitochondrial motility and in stability during a reduction in neuronal activity, it seems that two mechanisms could be required.
While crawling motion is often associated with a more controlled type of cell migration (Section 3.3.3), blebbing motility might allow for faster migration particularly in porous, 3D environments [ 342, 360].
To allow for direct comparison between cell invasion and cell motility, the invasive abilities of the cell lines were measured using the assay conditions optimised for the motility assay but with a coating of Matrigel on the filter separating the upper and lower compartment of the Boyden chamber.
Finding that DGKζ is upregulated in other metastatic cancers would suggest interfering with its function might allow for a more general role in inhibiting tumor cell motility and invasion.
However, there are important differences between the individual signaling molecules that allow for precise control of a full range of processes, including development, cell survival, differentiation, motility, angiogenesis, and carcinogenesis.
We also performed computer-assisted motility counting in three of the four countries (including Poland) but, unfortunately, the variability between countries in performing the analysis was too large to allow for between region comparisons.
The EDL was chosen to receive treatment because it allows for basic animal motility.
Bacterial motility allows for a number of beneficial activities, including acquiring more nutrients, maneuvering away from toxic substances, and colonizing in optimal environments [ 29].
Breakdown of the extracellular matrix (ECM) by Matrix Metalloproteinases encourages endothelial cell sprouting and allows for greater freedom in motility and invasion.
