Fig. 7. Role of N-cadherin in filopodia formation of myofibroblasts. (A) Bars show mean numbers of filopodia revealed by F-actin staining and counted on 50 myofibroblasts at the migration front (means of three results ± s.d.); asterisks indicated statistically significant difference. (B) Representative pictures of F-actin-staining of myofibroblasts at the migration front of cultures treated with control IgG1 or the GC-4 mAb. Bar, 25 µm (C) Representative pictures of F-actin and N-cadherin-staining at the migration front of myofibroblasts electroporated with control (con), or siN-CAD3 and siN-CAD4 oligonucleotides. Bar, 25 µm.
