Wound-healing scratch assay. Effect of recombinant human (rh)IL-17A and rhIL-17E on the migration, assessed by an in vitro wound-healing scratch assay, of myofibroblasts isolated from uninflamed areas of strictured (Strict uninfl) and non-strictured (Non-strict uninfl) gut of six patients with fibrostenosing Crohn’s disease (CD) and from normal gut of seven healthy control (HC) subjects. Myofibroblasts were cultured with rhIL-17A or rhIL-17E or medium alone. Results, expressed as percentage of wound repair, are mean ± SEM. *P<0.05 versus myofibroblasts cultured with medium only at 8, 16, and 24 hours.
