Figure 2. Influence of catS on the visco-elastic properties of BM matrix.

(A) G’ (elasticity: black symbol) and G” (viscosity: white symbol) moduli of BM matrix (ECM gel: 8 mg/ml) without (C: control, triangles), or with catS (60 nM, squares) were determined by rheometry. A representative of three independent experiments is shown. (B) Western blot analysis of major BM constituents of ECM gel (nid-1, perlecan, laminin and collagen IV) with or without catS.
