Two cardiac fibroblasts isolated from neonatal mice. The cell cytoskeleton is responsible for key cellular processes including cellular structure, cell movement, transport of molecules inside the cell and mitotic cell division. In here, both the microtubule network (green) and intermediate filaments (yellow/red) can be appreciated; in some cases originating from places near the nucleus (blue). Field width 0.1 mm.
