The expression of ALDH1 and CD133 in NSCLC tissues are positively correlated with the clinical features. (A-B) Statistical analysis of ratios of ALDH1+ and CD133+ in NSCLC specimens at different clinical stage using immunofluorescence (IF) and immunohistochemistry (IHC). (C) Representative images of IHC and IF assay of 33 primary NSCLC specimens, including stage I–IV lesions(200 ×). Each bar represents the mean ± SD of three independent experiments. Statistical significance level: p < 0.05.
