filopódíum
Filopodia are thin, actin-rich protrusions that extend from the cell membrane of various cell types, including fibroblasts, neurons, and immune cells. They are dynamic structures that constantly grow, retract, and explore the cellular environment. These finger-like projections are typically several micrometers long and only a few hundred nanometers in diameter.
The primary function of filopodia is cell sensing and exploration. They act as sensory organelles, detecting
The formation and behavior of filopodia are tightly regulated by the actin cytoskeleton. Actin filaments polymerize
