Figure 2From: The role of cytochrome c oxidase subunit Va in non-small cell lung carcinoma cells: association with migration, invasion and prediction of distant metastasis Differences in invasion ability among four NSCLC cell lines (H2126, CL1-1, CL1-5 and H2009). Invasion ability was assessed by Matrigel assay. Each bar represents the mean ± SD of the results from triplicates. The asterisk indicates a significant difference (P < 0.001) between either H2009 or CL1-5 and CL1-1 or H2009Back to article page
