Figure 1From: Pancreatic Stellate Cells (PSCs) express Cyclooxygenase-2 (COX-2) and pancreatic cancer stimulates COX-2 in PSCsImmunostaining of COX-2 and α-smooth muscle actin (α-SMA) in pancreatic stellate cells (PSCs) after one day in culture. (A) Immunostaining of COX-2 in quiescent PSCs. All PSCs stained for COX-2. (B) Immunostaining of α-SMA in quiescent PSCs. PSCs did not stain for α-SMA. Magnification 400×.Back to article page
