Milk at 10% does not affect the viability of in primary macrophages and RAW264.7 cells. Murine bone marrow-derived macrophages (A, B) and RAW264.7 cells (C, D) were incubated overnight with 1 to 100% pasteurized human (A, C; HM), and cow milk (B, D; CM). MTT conversion into solubilized formazan crystals was determined on a photometer. Mean values from at least four independent experiments are expressed as percentage of optical density in the treatment groups normalized to unstimulated control values.
