Figure 1: The dose-dependent response of CRC cells to LCSP. Colo320DM and SW480 cells were treated with increasing concentrations of LCSP as indicated and then incubated at 37°C for 24 h. Viable cells were trypsinized, stained with trypan blue, and counted under a microscope. Cell viability was expressed as a percentage of untreated cells. Data are the average of three independent experiments and are expressed as means ± SD.
