Location of the cytoskeleton
Witryna30 gru 2010 · By now it is abundantly clear that the cells of our bodies have the ability to move because of their actin cytoskeleton. From the earliest cell migrations in the embryo that serve to form the primordial tissue layers to the outgrowth of neurons, the contractions of our heart and skeletal muscles, and the metastasis of cancer cells, it is … The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including those of bacteria and archaea. In eukaryotes, it extends from the cell nucleus to the cell membrane and is composed of similar proteins in the various organisms. It is composed of three main components, microfilaments, intermediate filaments and microtubules, an…
