Human cytomegalovirus (HCMV) infectivity of primary human retinal pericytes. Phase contrast images of (A) an uninfected subconfluent monolayer of retinal pericytes, (B) a confluent monolayer of retinal pericytes and (C) pericytes 10 days after infection with the clinical strain SBCMV. Immunofluorescence staining of SBCMV-infected retinal pericytes for (D) major immediate protein (MIE) protein and (E) pp65 late stage protein. (F) Phase fluorescent overlay image of human retinal pericytes infected with a recombinant HCMV virus expressing GFP. All images were taken on a Nikon TE2000S microscope (200x magnification).
