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.

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.

3-Dimensional histological reconstruction and imaging of the murine pancreas

TL;DR: New methods for visualizing the whole murine pancreas and single islets of Langerhans are developed in an effort to gain a better understanding of how islet cell volume, spatial distribution, and vascularization are altered as diabetes progresses.

Spleen of the snake (Elaphe climacophora) and intrasplenic vascular architecture
TL;DR: The spleen of the blue‐green snake (Elaphe climacophora) lies at the head of the pancreas and is separated from it by a fibrous capsule, but the border could be distinguished clearly in silver‐impregnated specimens.
Journal ArticleDOI
Immunohistochemical analysis of pancreatic islets of platypus (Ornithorhynchus anatinus) and echidna (Tachyglossus aculeatus ssp.)
TL;DR: Overall, monotreme pancreata share the feature of consisting of distinct PP‐poor and PP‐rich islets with other mammals and may indicate a trend of having fewer larger islets comprising several endocrine cell types during mammalian evolution.

Immunocytochemical study of the endocrine pancreas in some species of Chalcides
TL;DR: In the endocrine pancreas of eight species of Chalcides four types of endocrine cells (designated A, B, D, and PP or F) were revealed by immunocytochemical methods, and it was suggested that this regional distribution of theendocrine cell types reflects the different emryonic origin of the two pancreatic lobes and/or different cell fun ctions.
