Figure 3. Reduction of Total Collagen Production in Laryngotracheal Stenosis (LTS)–Derived Fibroblasts.

Figure 3.

A, All 6 patient samples of LTS fibroblasts demonstrated reduced collagen production after interferon-γ (INF-γ) treatment. B, When compared as a group, INF-γ–treated fibroblasts had a significant reduction in the total amount of soluble collagen compared with untreated fibroblasts (10.94 vs 14.89 μg/mL; mean difference, 3.950 μg/mL; 95% CI, −4.753 to −1.419 μg/mL).

aP = .03 compared with untreated fibroblasts.
