Effect of HS-5 conditioned media (HS-5 CM) on CMV infection of HS-27a stromal cells measured as fluorescence intensity of GFP or as PFU. HS-27a cells were exposed to recombinant GFP-CMV at 0.2 MOI and cultured in control media (Control) or HS-5 CM for 13 days. Fluorescence intensity was determined using a CytoFluor plate reader; PFU were detected using an inverted fluorescence microscope. Data represent the means ± SE of four determinations in one of two representative experiments.
