PGCCs detection in CTH cultures. a An inverted light microscope was used to monitor the chronic CMV-transformed-HMECs (CTH)-BL and CTH-DB cultures, Magnification × 100, scale bar 100 μm. b Curves representing the PGCCs count detected in CTH cultures. The Y-axis represents the PGCCs count /well, and the X-axis represents the days post-infection. c. Time-course of the viral load in the CTH-DB and BL culture as measured by IE1-qPCR. Data are represented as mean ± SD of two independent experiments. Blue and orange curves represent the viral load (copies/ml) as measured by IE1-qPCR (Left Y-axis) and PGCCs count/well (Right Y-axis), respectively. The X-axis represents the days post-infection
