Figure 2From: The taccalonolides and paclitaxel cause distinct effects on microtubule dynamics and aster formationEffects of paclitaxel or taccalonolide A on mitotic accumulation and aster number. The number of mitotic cells present at each time after the addition of (A) 12 nM paclitaxel or (B) 5 μM taccalonolide A to GFP-β-tubulin expressing HeLa cells was counted. These mitotic cells were classified as containing bipolar spindles (black) or multiple asters (gray). Cells from 60 microscopic fields (20x) from 12 individual wells were analyzed for each condition at each time point.Back to article page
