Three-dimensional reconstruction of the embryonic pancreas in the grass snake Natrix natrix L. (Lepidosauria, Serpentes) based on histological studies
TLDR
The histological and 3D reconstructions suggest that the untypical topography of the organ systems in snakes may determine the unique development of the pancreas in these animals.About:

When the Pancreas
TL;DR: Dealing with sebaceous carcinoma is important prognostically but sometimes challenging with routine histopathology, androgen receptor (AR) was found to be confirmatory in only 36% of cases and not dependent on the size of the tumor available.
Journal ArticleDOI
Embryology of the VNO and associated structures in the grass snake Natrix natrix (Squamata: Natricinae): a 3D perspective
TL;DR: The main ophidian taxa (Scolecophidia, Henophidia and Caenophidia), just like other squamate clades, seem to be evolutionarily conservative at some levels with respect to the VNO and associated structures morphology.
Journal ArticleDOI
Embryology of the naso-palatal complex in Gekkota based on detailed 3D analysis in Lepidodactylus lugubris and Eublepharis macularius.
TL;DR: The embryological data confirmed recent findings about the nature of some developmental processes in squamates, for example, involvement of the lateral nasal prominence in the formation of the choanal groove and allows for redefinition of the anterior concha of Sphenodon.
Journal ArticleDOI
Do all geckos hatch in the same way? Histological and 3D studies of egg tooth morphogenesis in the geckos Eublepharis macularius Blyth 1854 and Lepidodactylus lugubris Duméril & Bibron 1836.
TL;DR: Egg tooth ontogeny in two gekkotan species, the leopard gecko Eublepharis macularius and the mourning gecko Lepidodactylus lugubris, was compared using microtomography, scanning electron microscopy, and light microscopy to reveal differences in egg tooth implantation between Gekkota and Unidentata.

The tetraspanin Tm4sf3 is localized to the ventral pancreas and regulates fusion of the dorsal and ventral pancreatic buds.
TL;DR: It is found that ventral pancreatic cells migrate extensively into the dorsal pancreas after fusion, whereas the converse does not occur, and that annular pancreatic tissue is composed exclusively of ventral Pancreas-derived cells.

Defekt- und Transplantationsversuche an der Anlage von Leber und Pancreas jüngster Amphibienkeime
TL;DR: Inhalts Verhalten des Leberimplantats gegeniiber dem Gef~l~netz eines artungleiehen Wirtes yon Leber und Pancreas fiber die Metamorphose hinaus, ernahrungsphysiologisehe Bedeutung des Blutstromes flit die Leberdifferenzierung.
Journal ArticleDOI
Immunocytochemical localization of four hormones in the pancreas of the garter snake, Thamnophis sirtalis.
TL;DR: The morphognomy of the secretory granules of the major endocrine cell types is qualitatively similar to that of mammals and whether or not the quantitative and/or associative differences contribute to the marked metabolic differences between reptiles and mammals, remains to be determined.

Close association of centroacinar/ductular and insular cells in the rat pancreas.
T S Leeson,R Leeson +1 more
TL;DR: Close contacts between endocrine insular cells and exocrine acinar, centroacinar and ductular cells occur frequently in the rat pancreas as seen by both light and electron microscopy.
Journal ArticleDOI
Developmental expression of survivin during embryonic submandibular salivary gland development
TL;DR: Immunohistochemical studies demonstrate nuclear-localized survivin protein in epithelial cells bounding forming lumina in Canalicular and Terminal Bud Stage SMGs, suggesting that survivin may be a key mediator of embryonic SMG epithelial cell survival.
