Comparison of spheroid formation of control and DPS-1-treated HDP cells. a Phase images of spheroid of control and DPS-1-treated HDP cells. Images were analyzed after 24 h of DPS-1 treatment. b The diameter of spheroid was quantified. Data are presented as the mean ± SD of results from three independent experiments. p < 0.001 is present as ****Back to article page
