Fox Lung Fibroblast Cells Expressing EGFP fused to Actin

Within the structure of the cell, actin serves three significant functions. It forms the most dynamic of the three subclasses of the cytoskeleton, which gives mechanical support to cells, and hardwires the cytoplasm with its surroundings to support signal transduction. Secondly, actin facilitates cell motility, the ability to move spontaneously and independently, in either single-celled or multicellular organisms. Thirdly, in muscle cells as well as non-muscle cells, actin helps generate force to support muscle contraction, vesicle movement, and other transport processes. In the digital videos presented above, normal Gray fox lung fibroblast cells (FoLu line) are expressing enhanced green fluorescent protein (EGFP) fused to human beta-actin.
