LL-37 enhances epithelial wound closure in a THCE cell monolayer. Growth factor–starved THCE cells were wounded with a pipet tip and allowed to heal in KBM containing 2 μg/mL LL-37. Wound closure was photographed immediately after wounding (0h) or 24 hours p.w. (24h). (A) Micrographs represent 1 of 3 samples performed each time. (B) Represents the statistical analysis of healing extent. Values are expressed as mean ± SEM (n = 3). **P < 0.01.
