CXCL9 and colonic neoplasm: To establish whether CXCL9, CXCL10, CXCL11 can modulate the growth/survival ability of the colon cancer cell line in culture, we examined and quantified cell growth after plating C26 and HT29 cells for 5 days at low density in base medium alone (serum starvation) or supplemented with various concentrations of CXCL9, CXCL10 or CXCL11.
