  1. Time: Cells were treated with chemotherapy for 24, 48 or 72 h. Drug: Cells were left either untreated (0) or were treated with three different concentrations of chemotherapy (1, 2, 3). Treatments: the number of repeated measurements from which means and standard deviations were calculated are indicated. DEX1, DEX2, DEX3: Non-drug treated cells (Drug 0) or drug-treated cells (Drug 1, 2, 3) were treated with three different concentrations of DEX. The value of 0 or 1 was assigned depending on whether or not the DEX group was declared resistant. There is a maximum score of 9 per time point for drug-treated cells. The basal effect of DEX (drug 0 row) was evaluated for its own and is not included in the sum column.
