Lamellipodia vs. Filopodia: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Published on January 9, 2024
Lamellipodia are broad, sheet-like cellular protrusions involved in cell movement, while filopodia are slender, rod-like extensions that sense the environment.

Key Differences

Lamellipodia are characterized by their broad, flat appearance, formed by a network of actin filaments. They play a crucial role in cell migration. Filopodia, in contrast, are thin, spike-like projections composed of parallel bundles of actin filaments and are essential for sensing the cellular environment.

The formation of lamellipodia involves the rapid polymerization of actin filaments at the leading edge of the cell, facilitating forward movement. Filopodia, on the other hand, extend from the plasma membrane and are involved in probing the surrounding matrix and initiating contact with other cells.

Lamellipodia are typically found at the leading edge of migrating cells, such as in wound healing or cancer cell invasion. Filopodia are often observed in neuronal growth cones, aiding in guidance and adhesion during neural development.

In lamellipodia, the actin network is more branched and less ordered, supporting their role in cell spreading. Filopodia, due to their tight actin filament bundles, are more rigid, allowing them to function as antennae for cells.

The dynamics of lamellipodia are regulated by various proteins, including those of the Rho family of GTPases. Filopodia formation is influenced by factors like Fascin and Ena/VASP proteins, which stabilize and extend the actin filaments.
