HCMV induces secretion of the angiogenic factors IL-6, GM-CSF, and IL-8. (A) ELISA quantification of IL-6 levels in 3 different supernatants of fibroblasts infected with HCMV AD169 and HUVECs infected with HCMV VR1814. (B) ELISA quantification of GM-CSF levels in 3 different supernatants of fibroblasts infected with HCMV AD169 and HUVECs infected with HCMV VR1814. (C) ELISA quantification of IL-8/CXCL8 levels in 3 different supernatants of fibroblasts infected with HCMV AD169 and HUVECs infected with HCMV VR1814.
