a. Fluctuations in mean aggregate size and paclitaxel levels over multiple passages of T. cuspidata P93AF cell suspension cultures. Passage is done every 14 days. Squares represent the mean aggregate size of the culture obtained through Coulter counter measurements. Circles represent paclitaxel content in the culture as measured through UPLC. b. Relationship between culture mean aggregate size and paclitaxel level. The Pearson correlation coefficient (r) is −0.75 (p < 0.05 as determined using a two-tailed test), indicating a statistically significant negative linear relationship. Data points represent three biological replicates. Horizontal bars represent standard errors of the mean aggregate size and vertical bars represent standard errors of the culture paclitaxel level.
