"Nettet1. aug. 1995 · It has also been reported that microtubules assembled in the presence of taxol tend to have 12, rather than 13, protofilaments [15], [16]. Taxol blocks the cell cycle in its G1 or M phases by stabilizing the microtubule cytoskeleton against depolymerization — the basis of its clinical use in cancer therapy.
