Pro-oxidative toxicity of cells in suspension does not point to a cell cultural artefact as an explanation of the increased susceptibility of alveolar epithelial-like cells after glucocorticoid pretreatment

•Pro-oxidative toxicity did not seem to be cell number dependent.•Increased toxicity of hydrogen peroxide in suspensions compared to monolayers.•Decreased toxicity of zinc chloride in suspensions compared to monolayers.•Zinc and tBHP pro-oxidative toxicity does not seems to be glutathione-dependent....
