Migration of isolated chondrocytes assessed using a Boyden chamber. The number of migrated chondrocytes was significantly larger in the medium supplemented with FBS than in medium without FBS. (*p < 0.05, **p < 0.01; Mann-Whitney U-test) (A). Among PDGF dimers, the number of migrated cells was larger in the presence of PDGF-AB and -BB than in the presence of PDGF-AA (*p < 0.05; Mann-Whitney U-test, **† < 0.05, One-way ANOVA and Bonferroni post-hoc test.)
