Caption Just as the skeleton and muscles move the human body and hold its shape, all the cells of the body are stabilised and moved by a cellular skeleton. 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. Now, a research team from the University of Göttingen is the first to succeed in observing a direct interaction between microtubules and intermediate filaments outside the cell, and also in quantitatively measuring this interaction.
