Figure 2. Increased CD90 expression (green) was observed on the activated fibroblasts in chronic pancreatitis.

(A) A representative image of pancreatitis tissue showed moderate expression of CD90 in fibroblast cells (indicated by arrows). (B) Fibroblasts around a duct (asterisk) showed distinctly strong expression of CD90 in pancreatitis. The insert is a higher magnification of the ductal area. Nuclei were stained with DAPI (blue). Scale bars  = 100 µm.
