“…Serotonin‐IR cells were also detected in gill filaments of the goldfish Carassius auratus auratus (L.), and increased after 1 week expose to lead intoxication (Franchini et al ., 1999). In addition, the ontogeny of serotonin‐IR cells and their changes during development were also monitored in the gut epithelium of the cloudy dogfish Scyliorhinus torazame (Tanaka)(Chiba, 1998) and the turbot Scophthalmus maximus (L.)(Reinecke et al ., 1997). It was also reported, however, that no serotonin‐IR cells were found in the gut of the goldfish (Pederzoli et al ., 1996) or in the GI tract of the Arctic lamprey Lampetra japonica (Mastens)(Yui et al ., 1988) and they were restricted to the nerve fibres in the latter species.…”

The regional distribution and relative frequency of neurohormonal peptides-producing cells were demonstrated in the gastrointestinal (GI) tract of the Korean aucha perch Coreoperca herzi, using 10 types of specific antisera raised against mammalian regulatory peptides. The GI tract was divided into four portions: stomach, gastro-intestinal junction, and small and large intestine. Most of the immunoreactive (IR) cells were in the mucosal epithelium and they were generally spindle shaped with a long cytoplasmic process. In addition, ovoid cells were found in the gastric regions. Serotonin-, somatostatin-, glucagon-, cholecystokinin-8 (CCK-8)-and pancreatic polypeptide (PP)-IR cells were observed with various relative frequencies. No chromogranin A-, secretin-, vasoactive intestinal peptide-, substance P-or bombesin-IR cells, however, were found. Serotonin-IR cells occurred throughout the GI tract and were the most numerous. Somatostatin-IR cells were restricted to the stomach and gastro-intestinal junction in numerous and moderate frequencies, respectively, but small numbers of glucagon-IR cells were restricted to the small intestine. Numerous CCK-8-IR cells were found in the small intestine but variable numbers of PP-IR cells occurred throughout the GI tract except for the large intestine. In general the distribution and relative frequency of these IR cells correspond well to previous reports in teleosts but there are some difference in this species. # 2004 The Fisheries Society of the British Isles

“…They were also detected in gill filaments of the goldfish and there, they increased after a 1‐week treatment of lead intoxication (Franchini et al., 1999). In addition, ontogeny of serotonin‐immunoreactive cells and their changes during development were also monitored in the gut epithelium of the turbot (Reinecke et al., 1997) and cartilaginous fish such as cloudy dogfish (Chiba, 1998).

The regional distribution and relative frequency of neurohormonal peptides-producing cells were demonstrated in the gut of the stomachless teleost, Zacco platypus (Temminck et Schegel), using 10 types of specific antisera raised against mammalian regulatory peptides. The gut of Z. platypus was divided into five portions from proximal to distal (segment I-V). Most of immunoreactive cells in the epithelial lining portion, between epithelial cells, were generally spherical or spindle shape having long cytoplasmic process that was reached via the lumen while cells round in shape were found in the basal portions of epithelial lining occasionally. Serotonin-, somatostatin-, glucagon-, cholecystokinin (CCK)-8 and pancreatic polypeptide (PP)-immunoreactive cells were observed in this study. However, no chromogranin A-, secretin-, vasoactive intestinal peptide (VIP)-, substance P- and bombesin-immunoreactive cells were found. Serotonin-immunoreactive cells were demonstrated throughout the entire gut tract and occurred more frequently than other cells. Somatostatin-immunoreactive cells were restricted to proximal segments of the gut (segment I-III) with rare frequencies, and glucagon-immunoreactive cells were demonstrated in the proximal segments of the gut (segment I, II) with moderate to few occurrences. CCK-8-immunoreactive cells were found throughout the whole intestinal tract except for most proximal segment (segment I) with moderate to few frequencies and PP-immunoreactive cells were demonstrated in the proximal to middle segments, segment I-III, with a few, rare and rare frequencies, respectively.

“…There have been many studies of the structure of the GEP system in euteleosts. The reader is referred to the extensive series of reports on GEP cells of the stomach, intestine, and islet tissue of the sea bass, Dicentrarchus labrax (Carrillo et al, 1986;Beccaria et al, 1990;Lozano et al, 1991a,b;Agulleiro et al, 1993;Gomez-Viscus et al, 1996, 1998, and the gilt-head sea bream, Sparus aurata (Abad et al, 1986(Abad et al, , 1987(Abad et al, , 1988(Abad et al, , 1992Elbal et al, 1991), where reviews of earlier literature are provided. It is important to highlight several other earlier morphological studies of islet tissue from euteleosts, for they are associated with the isolation of peptides and the production of antisera which greatly influenced subsequent directions of research on regulatory peptides in fish.…”

“…The endocrine cells of the gastrointestinal system of elasmobranchs has received a great deal of attention over the years and the reader is referred to several of the early and recent reports (El-Salhy, 1984;Cimini et al, 1989;Tagliafierro et al, 1989;Yui et al, 1990;Chiba et al, 1995;Chiba, 1998). However, despite the many species of elasmobranchs that have been investigated no phylogenetic pattern involving the presence/ absence or distribution of regulatory peptides in the stomach and intestine has emerged.…”

“…According to the latter authors, the early appearance of these peptides, and others (for example, vasoactive intestinal peptide, Tagliafierro et al, 1988), is support for the view that regulatory peptides play a role in cell growth and differentiation. Recently, there have been extensive studies on the ontogeny of NPY within the GEP system and vitellointestinal duct (VID) of embryos of Scyliorhinus torazame (Chiba et al, 1995;Chiba, 1998). Immunoreactivity for NPY was detected in the sac-like pancreas at the earliest embryonic stage, 15 mm long.…”

Ontogenetic and Phylogenetic Development of the Endocrine Pancreas (Islet Organ) in Fishes

The morphology of the gastroenteropancreatic (GEP) system of fish was reviewed with the objective of providing the phylogenetic and ontogenetic development of the system in this vertebrate group, which includes agnathans and gnathostome cartilaginous, actinoptyerygian, and sarcopterygian fish. Particular emphasis is placed on the fish homolog of the endocrine pancreas of other vertebrates, which is referred to as the islet organ. The one-hormone islet organ (B cells) of larval lampreys is the most basic pattern seen among a free-living vertebrate, with the two-hormone islet organ (B and D cells) of hagfish and the three-hormone islet organ (B, D, and F cells) of adult lampreys implying a phylogenetic trend toward the classic four-hormone islet tissue (B, D, F, and A cells) in most other fish. An earlier stage in the development of this phylogenetic sequence in vertebrates may have been the restriction of islet-type hormones to the alimentary canal, like that seen in protochordates. The relationship of the islet organ to exocrine pancreatic tissue, or its equivalent, is variable among bony, cartilaginous, and agnathan fishes and is likely a manifestation of the early divergence of these piscine groups. Variations in pancreatic morphology between individuals of subgroups within both the lamprey and chondrichthyan taxa are consistent with their evolutionary distance. A comparison of the distribution and degree of concentration of the components of the islet organ among teleosts indicates a diffuse distribution of relatively small islets in the generalized euteleosts and the tendency for the concentration into Brockmann bodies of large (principal) islets (with or without secondary islets) in the more derived forms. The holostean actinopterygians (Amiiformes and Semiontiformes) share with the basal teleosts (osteoglossomorphs, elopomorphs) the diffuse arrangement of the components of the islet organ that is seen in generalized euteleosts. Since principal islets are also present in adult lampreys the question arises whether principal islets are a derived or a generalized feature among teleosts. There is a paucity of studies on the ontogeny of the GEP system in fish but it has been noted that the timing of the appearance of the islet cell types parallels the time that they appear during phylogeny; the theory of recapitulation has been revisited. It is stressed that the lamprey life cycle provides a good opportunity for studying the development of the GEP system. There are now several markers of cell differentiation in the mammalian endocrine pancreas which would be useful for investigating the development of the islet organ and cells of the remaining GEP system in fish.
