Figure 2. Immortalised (VA) and further ras-transfected bovine pancreatic duct cells. RT-PCR (upper) and immuncytochemistry (lower) for collagen type I (COL I), collagen type IV (COL IV), laminin (LAM), fibronectin (FN), MMP2, TIMP2, and TSP1. GADPH: control. Analysis of the molecules was subject to the availability of bovine sequences and cross-reacting antibodies [12, 13].
