Aerotactic migration is impaired by antioxidants. (A) Aerotactic migration at 48 h of the indicated tumour cells either untreated (Mock), treated with 10 mM reduced glutathione (GSH) or 10 mM N-Acetyl Cysteine (NAC). Scale bars 0.5 mm. See Figure S4 for the other tumour cells. (B) Cell distribution from the centre of the cell cluster (in mm) at 48 h in the Mock condition (carmine, mean of three independent experiments), in cells treated with 10 mM GSH (blue) or 10 mM NAC (yellow). Y-axis scale is expressed in arbitrary unit
