IFN-gamma treatment inhibits the viability of mammary epithelial cells. Mammary epithelial MCF10A cells were treated with 500 u of IFN-gamma at seeding. Cell viability was measured using the MTS-assay on days 3 and 7 and the IFN-gamma/control quotient is demonstrated. Treatment with IFN-gamma produced a 59.5% (day 3) and 32% (day 7) reduction in viability as compared to control cells. The assay was performed in duplicate.
