Wound healing assay. Invasion and migration ability was investigated in the presence of nanaomycin K (5 µg/mL or 50 µg/mL) with or without TGF-β in KK47 and T24 cell lines (100 ×) up to 40 h cultures (A). Control cells were treated with DMSO (vehicle control). Representative figures are shown. Wound closures compared to the wound at 0 h were shown (B) (n = 4, average ± SE bars, *p < 0.05, **p < 0.01).
