What bones are to bodies, the cytoskeleton is to cells. The cytoskeleton maintains cellular structure, builds appendages like flagella and, together with motor proteins, powers cellular movement, transport, and division. Microtubules are a critical component of the cytoskeleton, vital for cell division and, because of that, an excellent target for chemotherapy drugs.
Microtubules can spontaneously self-organize, transforming from many singular components into one large cellular structure capable of performing specific tasks. Think Transformers. How they do that, however, has remained unclear.
Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have observed how microtubules and motor proteins assemble into macroscopic networks. Their observation provides a better understanding of cytoskeletal self-organization in general, which may in turn lead to better drug design and new materials that can mimic cellular behaviors.
