Indole extract showed no cyctotoxic effect on fibroblast cells. Cytotoxicity assay on human fibroblast cells after 24 h exposure to the nutrient medium interacting with indole extract (0.6 mg/mL), impregnated catheter with extract (0.6 mg/mL) and control catheters on human fibroblast cells. Cytotoxicity was determined by MTT assay and represented as the percentage of remaining viable cells after treatment.
