Immunofluoresence for NEUROG3 in human fetal pancreas. (AE) Immunofluorescence for NEUROG3 at 14 wpc. (A) Arrowheads point to green PCNA-positive cells while arrows point to separate red NEUROG3-positive cells. (B) and (C) Arrows point to hormone-negative NEUROG3-positive cells. Arrowhead points to a very rare NEUROG3-positive cell with faint somatostatin (SS) staining. (D) and (E) Arrowheads point to NEUROG3-positive nuclei visible in (D) but not (E) following pre-incubation with full-length human NEUROG3 protein. Amplification of the red gain with DAPI counterstaining to investigate the loss of nuclear staining has introduced some background cytoplasmic staining. Scale bar represents 50 μm.
