BMCM reverses As₂O₃-induced inhibition of colony formation. Cells were seeded at 500 cells/ml in semi-solid non-adherent cultures ± As₂O₃ and/or BMCM at the above concentrations. Colonies were counted after 8–10 days of incubation. All determinations were done in triplicate and are presented as mean ± SD
