Table 2.
Extent of Dye Coupling Between Non-CF and CF Airway Epithelial Cells
| Number of labeled cells | Beas2B | CF15 | IB3-1 | |||
|---|---|---|---|---|---|---|
| Control* | TNF-α† | Control | TNF-α | Control | TNF-α | |
| 1–2 | 7 (20) | 17 (63) | 2 (7) | 3 (16) | 5 (20) | 1 (7) |
| 3–4 | 7 (20) | 9 (33) | 8 (30) | 1 (5) | 6 (24) | 3 (23) |
| > 5 | 21 (60) | 1 (4) | 17 (63) | 15 (79) | 14 (56) | 9 (70) |
*Values indicate the number of microinjections. Percent values are given in parentheses.
†TNF-α (100 U/ml) decreased the proportion of dye coupled Beas2B (non-CF) cells but not that of CF (CF15 and IB3-1) cells.
