Figures

FIG. 1.
FIG. 1.
Neogenesis in mouse pancreas. A: The metaplastic ducts seen in the zinc-treated metallothionen. TGF-α transgenic mice have 6% insulin+ (red, white arrows) cells and some amylase+ (green, yellow arrow) cells. Tissue from study reported in (37); the background in the red channel was enhanced to see the context of the ducts. Magnification bar = 100 μm. B: After partial (70–80%) pancreatectomy in adult mice, insulin+ (blue) cells “budding” from proliferating ductules labeled with E-cadherin (red) are found in well-defined areas termed foci of regeneration that further differentiate into new lobes of pancreas (40). Magnification bar = 50 μm. (A high-quality digital representation of this figure is available in the online issue.)
FIG. 2.
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.)
