M2 exosomes promote LC cell growth. a F4/80 positive expression in LC tissues and adjacent normal tissues was detected using immunohistochemistry; b miR-501-3p expression in A549 and SPC-A1 cells detected using RT-qPCR; c proliferation of A549 and SPC-A1 cells detected by CCK-8 assay; d colony formation ability of A549 and SPC-A1 cells detected by colony formation assay; e apoptosis of A549 and SPC-A1 cells detected by flow cytometry; f migration ability of A549 and SPC-A1 cells detected by scratch assay; g invasion ability of A549 and SPC-A1 cells detected by Transwell assay; N = 3; the measurement data were expressed as mean ± standard deviation and unpaired t-test was performed for comparisons between two groups
