Effect of overexpression of Id2 or its mutants on the migratory capacity of MCF-7 and SKOV-3 cells. Migratory behaviors of Id2 or its mutant transfectants were determined by scratch-wound assay (top panel) and quantified as described in "Methods" (bottom panel). The scratch area at 0 h was arbitrarily assigned as 100%. (*P < 0.05; # P <0.01; N P > 0.05).
