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.

Vertebrate endoderm development
James M. Wells,Douglas A. Melton +1 more
TL;DR: Possible mechanisms that regulate how undifferentiated endoderm becomes specified into a myriad of cell types that populate the respiratory and gastrointestinal tracts are discussed.
Journal ArticleDOI
Pancreas organogenesis: from bud to plexus to gland.
TL;DR: Findings in the past 5 years that are amongst the most significant in contributing to the deeper understanding of pancreas development are summarized and highlighted to highlight interesting new concepts, and to discuss provocatively some of the more controversial findings or proposals.

An ultrastructural analysis of the developing embryonic pancreas

TL;DR: The morphological observations of this study are consistent with the previously proposed biphasic model of differentiation for the exocrine and endocrine B cells, and the development of specific organelles correlates with the pattern of accumulation of the specific exocrine proteins and insulin.

Pancreatic organogenesis--developmental mechanisms and implications for therapy.
Helena Edlund,Helena Edlund +1 more
TL;DR: The pancreas is a mixed exocrine and endocrine gland that controls many homeostatic functions and any attempt to generate functional insulin-producing β-cells that are suitable for transplantation is crucial for understanding the development and homeostasis of this organ.

Fgf10 is essential for maintaining the proliferative capacity of epithelial progenitor cells during early pancreatic organogenesis
Anil Bhushan,Nobuyuki Itoh,Shigeaki Kato,Jean P. Thiery,Paul Czernichow,Saverio Bellusci,Raphael Scharfmann +6 more
TL;DR: It is demonstrated here that Fgf10, a member of the fibroblast growth factor family (FGFs), plays an essential role in the normal development of the pancreas and should prove useful in devising methods to expand pancreatic progenitor cells.
