Figure 2

Immunohistochemical staining results of pancreatic ductal–epithelial cell aggregates (day 0) prior to mesenchymal cell expansion. Pancreatic ductal cell aggregates stained positive (a) for the ductal–epithelial cell marker CK19; one aggregate in the field is positive for insulin (b) and amylase (c) staining. Positive immunoperoxidase stain is brown and hematoxylin counterstain is blue. Scale bar represents 50 μm.
