dynamic network of actin filaments supporting cell shape and movement
The actin cytoskeleton, also known as the actin filament network, is a dynamic structure composed of actin proteins that form filaments within cells. It plays a crucial role in maintaining cell shape, enabling cell movement, and facilitating various cellular processes such as division and intracellular transport. This network is essential for the structural integrity and functionality of cells, including those involved in hair growth and maintenance.
