The inner cell mass looks more or less homogeneous; most of the cells have a similarly elongated shape with numerous pseudopodia (filopodia) (Fig.
In fact, we found that cells in normoxic conditions treated with S1PR1 antagonist W146 showed a reduction of MMP-2 expression/activity as well as of F-actin assembly and the disappearance of plasma membrane-associated F-actin structures, such as lamellipodia-like structures, filopodia, and small punctate structures (microspikes) associated with a decrease of cortactin expression, similarly to the cells treated with a specific MMP inhibitor.
"Tip" cell localized at the forefront of vessel branches shows highly polarized nature and numerous filopodia probing the environment, while migrating toward an angiogenic stimulus.
Another important characteristic about actin, is the fact that is essentially regulated during cell migration, cell adhesion, cell division, and several other essential cellular functions, because actin is part of the configuration of many cellular structures including filopodia, lamellipodia, microvilli and stress fibers (Zhu, Zhang, Hu, Wen and Wang, 2013).
Cells move using leg-like protrusions called filopodia, but cancer cells produce far more of these than healthy tissue.
These authors concluded that BK stimulates a conformation of the filopodia type for the cell membrane, which is vital to the migration process.
However, immature pyramidal neurons express highly motile filopodia and lack spines.
Microvilli or villous filopodia extend into the glandular lumens or intercellular spaces created by these groupings.

As the effector of Rho GTPase, PAK4 controls the cytoskeleton primarily through the regulation of polymerized actin structures, particularly the formation of filopodia and lamellipodia, but can also act upon microtubule organization [9].
