Fig. 2From: Tumor-associated macrophages modulate resistance to oxaliplatin via inducing autophagy in hepatocellular carcinomaCo-culturing with macrophages enhance oxaliplatin-resistance in HCC cells. a HCC cells were co-cultured with macrophages by Transwell system. b SMMC-7721 and Huh-7 cell viability was investigated by MTT assay. c The percentage of apoptotic SMMC-7721 and Huh-7 cells was determined with Annexin V staining assay. Data shown are mean (SD) from at least 3 independent experiments. Means were compared between two groups using unpaired, two-tailed Student’s t-test. * P < 0.05, ** P < 0.01Back to article page
