Lamellipodia is a type of cellular structure that is found on the surface of certain animal cells, including fibroblasts, epithelial cells, and neutrophils. It is a sheet-like extension of the cell membrane that is involved in cell migration, adhesion, and signaling. Lamellipodia are formed when actin filaments and microtubules interact with the cell membrane, creating a dynamic and flexible structure that can change shape and move in response to external cues. They play a critical role in various cellular processes, including wound healing, tissue repair, and immune responses.
