Validation of Putative Endocrine Precursor Cells in Ductal Subpopulations by Antibody Staining
(A and B) Antibody staining for INS and FTH1 in human pancreatic showing a single cell positive for INS and FTH1 residing in the lining of the duct (arrow).
(B) Antibody staining for INS, FTH1, and GCG in human pancreatic tissue. Shown is a single cell positive for INS and FTH1 residing in the lining of the duct (arrow) next to a GCG-expressing cell (arrowhead). Another GCG-expressing cell is found nearby (arrowhead). Both GCG-expressing cells are FTH1-negative.
