|---|---|---|---|---|
| Apical | Basal | Cell junctions | Total | |
| Parental | 406 (13.1) | 242 (7.8) | 140 (4.5) | 788 (25.4) |

a
Parental LLC-PK-1 cells or stably transfected cells expressing μ1B were grown on plastic coverslips and infected with wild-type PRV for 16 h Cells were then fixed and processed for electron microscopy as described for Table 1.
