Dose-dependent inhibition of As2O3-induced cell death by BMCM (at concentrations indicated in the box) in non-adherent cultures of: a Anchorage-dependent N-type cells. b Anchorage-independent I-type cells. c Anchorage-dependent S-type cells. Viability was quantified, using the XTT reagent by colorimetric measurement of mitochondria-mediated tetrazolium salt reduction, resulting in colored formazan compounds. The results (mean ± SD) of triplicate cultures represent absorbance at 450 nm after 5 h incubation with XTT
