[CYTOPLASMIC LOCALIZATION OF NEUN/Fox-3 NUCLEAR PROTEIN IN THE PANCREATIC CELLS]

The study of the sections of Wistar rat pancreas (n=4) using the methods of immunocytochemistry and confocal laser microscopy has demonstrated previously unknown fact of the presence of NeuN protein in the secretory epithelial cells of the exocrine part of this organ. The protein was located in the apical part of the cytoplasm slightly below the zone of zymogen granules. Until now the nuclear protein NeuN was considered to be the panneuronal differentiation marker and was used in the studies of neurogenesis.
