Figure 2From: N-Methyl-N'-nitro-N-nitrosoguanidine-induced senescence-like growth arrest in colon cancer cells is associated with loss of adenomatous polyposis coli protein, microtubule organization, and telomeric DNASenescence associated β-Galactosidase staining in HCT-116 cells treated with MNNG. HCT-116 cells were fixed after treatment either with 50 or 100 μM MNNG and processed for β-galactosidase staining as described in Materials and Methods. Stained cells were observed under the microscope and images were captured.Back to article page
