Two different cellular filaments (cyan and red) are attached to microscopic beads (yellow). The particles are held in place with the help of laser beams (orange and red beams). The filaments are crossed and then moved over each other as if playing a violin. They can interact so strongly that one of the filaments is bent (blue).

Unlike our skeleton, this cellular skeleton is a very dynamic structure, constantly changing and renewing itself. It consists of different types of protein filaments, which include intermediate filaments and microtubules.
