Filopodia (sg.: filopodium) are slender cytoplasmic projections that extend beyond the leading edge of lamellipodia in migrating cells. [1] Within the lamellipodium, actin ribs are known as …

2008年5月9日 · Filopodia are thin, actin-rich, finger-like structures that are involved in numerous cellular processes, such as cell migration, wound healing, neurite outgrowth and embryonic …

2023年11月30日 · Filopodia are dynamic structures that are primarily composed of F-actin bundles and whose initiation and elongation are precisely regulated by the rate of actin …

2024年7月4日 · Filopodia, widely distributed on cell surfaces, are distinguished by their dynamic extensions, playing pivotal roles in a myriad of biological processes. Their functions span from …

2001年8月21日 · Filopodia are thin, dynamic cell extensions comprising tight bundles of long actin filaments covered with cell membrane. They can change their length rapidly, span many cell …

Filopodia are long, slender, actin-rich cellular protrusions, which recently have become a focus of cell biology research because of their proposed roles as sensory and exploratory organelles …

5 天之前 · Abundant filopodia are characteristic of invasive cancer cells and high expression of filopodia regulators such as fascin and myosin-X are associated with cancer progression (Cao …

Filopodia are actin-based structures composed of parallel bundles of actin filaments and various actin-associated proteins, and they play important roles in cell-cell signaling, guidance toward …

Filopodia are found in many different cell types and broadly vary in morphology. They often display not only protrusive, retractile, and sweeping motility, but also exist as stationary …

Numerous F-actin containing structures are involved in regulating protrusion of membrane at the leading edge of motile cells. We have investigated the structure and dynamics of filopodia as …
