Effect of DHK on migration of KSCs. Note that DHK significantly increased migration of KSCs. Photographs were taken 24 h after wounding (a: control, b: 50 μm DHK treatment). Black lines indicate the initial wound after scraping. Migration distance was increased by DHK treatment in a dose‐dependent manner (c). Increased cell migration was reversed by specific Akt (LY294002, 5 μm) and ERK1/2 (U0126, 5 μm) inhibitors (d). **P < 0.01.
