Function of miR-144-3p in A549 cells. a Proliferation of A549 cells transfected with control or miR-144-3p mimics together with HGF was detected by CCK-8 assay. *P < 0.05 versus negative control miRNA mimics (miR-NC). ^##P < 0.01 versus miR-144-3p + Vector. b Flow cytometry was used to analyze the cell cycle. *P < 0.05 versus miR-NC. ^##P < 0.01 versus miR-144-3p + Vector. Representative images and counts of cell migration following transfection with control or miR-144-3p together with HGF, c Transwell assay and d Wound-healing assay. *P < 0.05 versus miR-NC. ^##P < 0.01 versus miR-144-3p + Vector. Scale bar = 25 μm. miR-NC, miR-144, miR-144 + vector and miR-144 + HGF need to be explained in a figure
