LAMB2 and pancreatic adenocarcinoma: To examine the composition of the tumour stroma of human pancreatic adenocarcinoma, we stained histological sections of pancreatic cancer patients for laminin-α3 chain and for tenascin-W, both markers for the extracellular matrix (ECM) (Figure 1A), as well as for NG2, a characteristic marker of CAFs (Figure 1B).
