Fig 5. Constructs exposed to different experimental conditions showed different features.

Hematoxylin/eosin sections of matrices in (a) control, (b) air-lifted, (c) partially desiccated, or (d) IL-13-treated conditions. Magnification: X20. (e) Matrix thickness was measured in the different experimental conditions. (f) The inflammatory cytokine IL-6 was secreted by conjunctival cells in the fibrin scaffold. In air-lifted (AL) and in partially desiccated cultures, IL-6 levels were significantly increased. Mean values from 6 independent experiments. **p ≤ 0.01; ***p ≤ 0.005.
