CXCR4 expression in lung adenocarcinoma patients according to EGFR-L858R mutation status.
The CXCR4 surface protein expression in lung adenocarcinoma cells from EGFR-L858R and EGFR-WT tumors was determined by flow cytometry. Box shows median and interquartile range ± 95% confidence interval. Patient samples were tested in triplicate (*P = 0.025, Mann-Whitney U Test).
