Figure 3From: Isolation and genetic characterization of human coronavirus NL63 in primary human renal proximal tubular epithelial cells obtained from a commercial supplier, and confirmation of its replication in two different types of human primary kidney cellsCytopathic effects in LLC-MK2 and MDCK cells inoculated with spent BGM from 5-day RPTEC cultures. [A]. LLC-MK2 cells, 5 days p.i. 37°C (400X); vacuolated single cells and vacuolated syncytium are evident. [B] Foci of vacuolated LLC-MK2 cells, 4 days pi, 37°C (400X). [C,D] LLC-MK2 cells with large syncytia but few vacuoles, 5 days pi, 34°C (200X).Back to article page
