This was a clever move to ensure continued public support for this endeavor, which had been justified previously by the prospect that it would lead to the diagno...

Microtubule dynamics: Treadmilling comes around again

Although it is generally believed that microtubules have minus ends bound to the centrosome and free plus ends that exhibit dynamic instability, recent observations show that the minus ends can be free and that modulation of dynamic instability at both ends can result in treadmilling and flux in interphase cells.
