 A scratch assay showed a delayed process of wound healing. (a) Images of untreated and 4 mg/mL Huaier‐treated MCF‐7 cells were taken at 0, 12 and 24 h. (b) Wound healing was defined as the percentage of the starting distance between the two edges of each wound. The Huaier‐treated MCF‐7 cells showed a slower rate of wound closure than the control cells. (c) Images of the MDA‐MB‐231 cells with and without administration of Huaier (4 mg/mL) taken at 0, 12 and 24 h. (d) The distance between the two edges of the scratch in the Huaier‐treated well was greater than that of control.
