(a) Morphology of drug-resistant cell lines. Cell nuclei were stained with DAPI, and actin filaments were stained with phalloidin-Alexa Fluor 594. (b) Quantification of the area of TNBC cell lines. The cell areas were measured from three distinct cells in the image. Data are expressed as mean ± SD (n = 3). Significant differences between groups were determined using the Welch’s t-test (*p < 0.05 and **p < 0.01)
