Figure 14. Both control paclitaxel and post-fabrication paclitaxel induce a significant decrease in the cell count. Cells (EJ, A549 or U87) were plated at a density of 10 × 103 cells/well in a 24-well plate in tetraplicate (n = 2). One day after plating, 0.1% DMSO (control), 50 μM control paclitaxel (black columns), or 50 μM post-fabrication paclitaxel (white columns) were added for 24 h. The cells were then counted using a hemocytometer (*p < 0.01 compared with the control well). Paclitaxel's effect on the above-mentioned cell lines is presented in terms of mean cell viability ± standard deviation.¹³³
