In view of cell distribution differences in mammalian islets of ventral and dorsal primordia, we have determined the percentage volumes of insulin\u2010, glucagon\u2010, and somatostatin\u2010containing cells in primary and secondary catfish islets to ascertain if these islets correlated with those derived from ventral and dorsal primordia in mammals. Islets were immunocytochemically stained using antisera to anglerfish insulin, porcine glucagon, and synthetic somatostatin and volume densities were quantified on light micrographs by point\u2010counting procedures. In both primary and secondary islets the insulin\u2010, glucagon\u2010, and somatostatin\u2010containing cells comprised approximately 32%, 23%, and 38% of the endocrine cell volumes, respectively. Therefore, the cell populations did not reflect any embryological differences between the two groups of islets. In this study, the volume densities of insulin\u2010reactive cells in the primary islet were less than previously reported, and the overall insulin staining was about one\u2010half of that seen in mammals. The volume density of somatostatin\u2010reactive cells in primary islets was greater than previously reported. Based on these data, primary and secondary islets of the catfish do not appear to have a similar development to the ventral and dorsal islets of the mammalian system.<\/jats:p>","DOI":"10.1002\/ar.1092090317","type":"journal-article","created":{"date-parts":[[2005,2,26]],"date-time":"2005-02-26T23:37:07Z","timestamp":1109461027000},"page":"381-384","source":"Crossref","is-referenced-by-count":12,"title":["An immunocytochemical study of the pancreatic islet system of the channel catfish"],"prefix":"10.1002","volume":"209","author":[{"given":"Daniel L.","family":"McNeill","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jack E.","family":"Brinn","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donald J.","family":"Fletcher","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,1,26]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.390711"},{"key":"e_1_2_1_3_1","first-page":"277","article-title":"The pancreatic islet cells of the channel catfish (Ictalurus punctatas)","volume":"172","author":"Brinn J.
