In vitro migratory ability of ADSCs. (A) Parental ADSCs, TRAIL-ADSCs or HFFs were co-cultured with A375 in a Transwell system for 24 days and the migrated cells were stained with crystal violet. Magnification, ×100. (B) Quantification of data. Values were from three independent experiments and were presented as the mean ± standard error of the mean. The cell number of each filter membrane was obtained from an average of five randomly selected microscopic fields. ^*P<0.05 vs. HFF. TRAIL, tumor necrosis factor-related apoptosis-inducing ligand; HFFs, human foreskin fibroblast; ADSCs, adipose-derived stem cells.
