Tolerance of bacteriophage in vitro. Metabolic activity of hMSC populations exposed to ΦPaer14 for 24,48, and 72 hr, normalized to the activity of populations grown in the absence of ΦPaer14 for the same period of time. Two-way ANOVA with Tukey’s post hoc comparison test comparing each ΦPaer14 group to the untreated group at the same time point. Mean ± SD, n = 6 per group, *p < 0.05
