Celastrol disorganizes mitotic spindles.

The representative immunostaining of microtubule (alpha- tubulin) and centrosome (gamma-tubulin) of the interphase and spindle morphology of mitotic HeLa cells treated for 1 hour with the indicated drugs; Celastrol (4 µM), Vinblastine (10 nM), and Taxol (10 nM).
