Wound healing assay for anticancer activity of Taxol, cisplatin, STE, RE, and combinations at 96 hours. Wound healing assay at 96 hours following treatment with (a) STE, RE, and combination; with (b) cisplatin and cisplatin-extract combinations; with (c) Taxol and Taxol-extract combinations. Bars represent the average wound closure distance for each group (n = 4) in MDA-MB-231 cells. Error bars represent the positive and negative standard deviation values of each group. , , , and compared to the control. ^‡, ^‡‡, ^‡‡‡, and ^‡‡‡‡ compared to cisplatin alone. ^†, ^††, ^†††, and ^†††† compared to Taxol alone. Micrographs represent the overlay of fluorescence and brightfield images at 100x magnification. Scale bar is 100 μm. Each micrograph is representative of four independent experiments.
