Lamellipodia

Lamellipodia are thin, sheet-like extensions of a cell's membrane that play a crucial role in cell movement and shape. They are made up of a network of actin filaments, a type of protein that helps provide structure and support. Cells use lamellipodia to crawl along surfaces, which is essential for processes like wound healing, immune responses, and tissue development. By spreading out and attaching to surfaces, lamellipodia enable cells to maneuver through their environment and communicate with other cells for various biological functions.
