As typical of growing neurons, Drosophila primary neurons display prominent growth cones at the tips of their axons, which display highly dynamic motility needed to direct axon extension.
During cell motility, cells need to generate transcellular contractile forces to retract the trailing uropodia.
The role of RhoA and its effectors ROCK in mesenchymal motility is complex; their activity needs to be reduced to extend protrusions at the front of the cell [ 59], but they promote the retraction of the lagging tail [ 57].
However, certain requirements need to be accomplished for the application in this field: the sperm cell needs to maintain its motility and fertilization capability throughout the whole delivery process.
However, it needs to be considered that motility of myosin-17 might be very slow under in vitro conditions, but faster in the living cell, thereby supporting exocytosis by short-range motility near the plasma membrane.
For controlled cell motility, the formation and disassembly of adhesion sites needs to be coordinated.
Specifically, the microenvironment of the primary tumor needs to support tumor cell dissemination, motility, and local invasion into the vasculature (intravasation), whereas the microenvironment at the secondary site needs to support cell adhesion, proliferation, and neovascularization.
However, role of β1,6 branched N-oligosaccharides on the motility receptors in regulating their association with MT1-MMP needs to be assessed.
Owing to the requirement for almost weekly operations and daily dressing changes, enteral nutrition needs to be stopped occasionally - further disrupting the gastrointestinal motility, and complicating adjustments [ 15].
