FIG 6.

HAd4V-41 stimulates GFAP expression by EGCs. (A) Confocal microscopy images of GFAP immunofluorescence staining of EGCs stimulated with purified HAdV-41, serotonin, cell supernatant from HAdV-41-infected EC cells, and cell supernatant from uninfected EC cells. (B) GFAP immunofluorescence intensity of cells stimulated with purified HAdV-41, serotonin, cell supernatant from HAdV-41-infected EC cells, and cell supernatant from uninfected EC cells. MEM, minimum essential medium; UN, cell medium (MEM) from unstimulated cells. ***, P < 0.001 by Student's t test. Data are means ± SEM (n = 30).
