Wound closure was performed as previously described[17 (link)]. Mitomycin C (10 μg/mL) was added to the cell culture medium to prevent cell proliferation during migration in the wound healing assay[6 (link),17 (link)]. Wound healing/closure was monitored by assessing the migration of cells for 24 h; photographs were taken at 0 and 24 h with a digital SPOT camera attached to an inverted Nikon phase-contrast microscope. The images were stored in TIF format and processed in Adobe Photoshop (Adobe Systems Inc., Mountain View, CA, USA).
