Figure 2. Effects of 15-d-PGJ₂ and troglitazone on cell viability. Cells were incubated with various concentrations of 15-d-PGJ₂ and trogiltazone for 36 hrs (A) and with 20 µM 15-d-PGJ₂ and troglitazone for the indicated periods of time (B). Cell viability was determined by a modified MTT assay and expressed as a percentage of viability under control culture conditions. Data are expressed as mean ± SD (n = 3). *p < 0.05, **p < 0.01.
