Example sentences for: protrusions

How can you use “protrusions” in a sentence? Here are some example sentences to help you improve your vocabulary:

Previously, Steimle and colleagues [ 23 ] reported that in interphase cells, during chemotaxis, random migration, and endocytic/phagocytic events, MHCK-A is recruited preferentially to anterior F-actin rich protrusions.
Taken together, the experiments performed by Rustom and colleagues strongly suggest a role for cell protrusions in cell-to-cell communication.
The first physical step in directional motility is the extension of cellular processes termed pseudopods [ 11 ] . Pseudopodia are flattened, fan shape cellular protrusions enriched in signaling molecules and cytoskeletal elements including filamentous actin, which is preferentially nucleated at the leading edge of a migrating cell [ 12 ] . A key candidate for regulation of the T lymphocyte actin cytoskeleton is the GTP-binding protein Rho.
Fusion between two protrusions is reported to rely on the cylindrical shape and narrow diameter of cell protrusions and also on the localised concentration of adhesion/fusion molecules at the tips of the cell protrusions, such as microvilli, that display particular tip-specific membrane microdomains (Monck and Fernandez 1996; Wilson and Snell 1998; Roper et al.
Thus far, the function of cell protrusions has been hypothesized mainly on the basis of their location in tissues and on crude attempts to remove them, for example by altering the actin cytoskeleton or even by removing the entire epithelium they belong to.
