FIG. 2.
Neogenesis in adult human pancreas. Insulin+ (brown) cells seen in the ducts in adult human pancreas. A: Surgical sample from patient who had partial pancreatectomy due to recurrent postprandial hypoglycemia after gastric bypass as reported in Patti et al. (79). While no Ki67+ islet cells were seen in sections from this pancreas, many ductal cells were Ki67+ (not shown) and many insulin+ cells are seen within the ductules. Magnification bar = 100 μm. B: Insulin+ cells are found within the ductal epithelium in human pancreas. Magnification bar = 20 um. (A high-quality digital representation of this figure is available in the online issue.)
