Frequency of pancreatic leukocytes. Leukocytes, as revealed by their unspecific binding of the secondary antibodies, their small size, and their characteristic nuclei, were clearly more frequent (more than doubled by cell counting) in all the sampled pigs from the Cereal group (A and C, n = 5) as compared to all the sampled pigs from the Paleolithic group (B and D, n = 5), with no overlapping between groups. These cells usually occurred scattered throughout the exocrine pancreatic parenchyma or clustered around pancreatic ducts (A and B) and blood vessels (C and D).
