Lack of Norovirus Replication and Histo-Blood Group Antigen Expression in 3-Dimensional Intestinal Epithelial Cells
Figure 5. . . Lipopolysaccharide (LPS) induces morphologic changes consistent with cytopathic effects in Norwalk virus–inoculated 3-dimensional INT-407 aggregates. Two independent sets of light microscopy images show 3-D intestinal aggregates treated with increasing concentrations of LPS for 24 h. Arrows indicate cells (or cellular debris) that were released from the support beads. Original magnification ×20.
