The complete growth medium used for the CT26 cell culture was the Roswell Park Memorial Institute (RPMI) culture medium (Hyclone, USA) and that for the HCT116 cell culture was McCoy’s 5A medium (Sigma-Aldrich, USA), supplemented with 10% Foetal Bovine Serum (FBS) (Gibco, USA) and 1% Penicillin-streptomycin (Gibco, USA).

Cancer Res. (The 2D monolayer cultures of CT26 and HCT116 cells were exposed to varying concentrations of IB and the cell proliferation rate was expressed as a percentage of the control. The unique physiology of solid tumors: opportunities (and problems) for cancer therapy. Cell. On the other hand, the inhibitive effect of CM is significant, with the cell proliferation of CT26 spheroids decreasing to 20.0% and that of HCT116 spheroids decreasing to 17.0% after 72 hours (In an attempt to determine if proteins are involved in the previous observations, CM was boiled to denature the proteins and obtain boiled conditioned media (BCM). The spherical morphology of the control spheroid was not observed in the IB spheroid, which appeared deformed (Comparison between morphology of CT26 Control spheroid and spheroid exposed to IB after 24 hours.Images taken with scanning electron microscope (SEM). 318, 1577–1585 (2012).Anand, P., Fu, A., Teoh, S.
