1. Primary GBM cells are permissive to HCMV in vitro.
Primary GBM cells are permissive to HCMV in vitro. (A) GBM 112 and GBM 114 cells were infected with HCMV TB40/E-mCherry at the indicated MOI for 24 h and then analyzed by flow cytometry for mCherry expression (brown histograms). Mock-infected cells (gray histogram) served as a control. The image is representative of three biological replicates. (B) The average percentage of mCherry-positive (HCMV-infected) cells at 1 day (D1) or 7 days (D7) postinfection for three biological replicates of the experiment presented in panel A are presented. Error bars represent the standard errors of the means for the three biological replicates. (C) GBM 112 spheres infected for 5 days at a MOI of 1.0 with HCMV TB40/E-mCherry (red) and counterstained with 4′,6′-diamidino-2-phenylindole (DAPI) (blue) were imaged by confocal fluorescence microscopy. (D) GBM 112 spheres infected for 7 days at a MOI of 1.0 with HCMV TB40/E-mCherry (red) were imaged by conventional fluorescence microscopy. (Left) Bright-field image; (center) dark-field fluorescence image; (right) bright-field fluorescence image.
