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:

Development of endocrine pancreatic islets in embryos of the grass snake Natrix natrix (Lepidosauria, Serpentes).
TL;DR: Four phases of islet formation are observed: differentiation of individual endocrine cells from the progenitor layer of duct walls (budding) and their incomplete delamination, joining groups of cells emerging from neighboring ducts (fusion) and rearrangement of cells within islets; (d) differentiated pancreatic islets with characteristic arrangement ofendocrine cells.
Journal ArticleDOI
Ultrastructure of endocrine pancreatic granules during pancreatic differentiation in the grass snake, Natrix natrix L. (Lepidosauria, Serpentes).
TL;DR: Different morphological subtypes were recognized that indicated their maturity, which may be related to the different content of these granules during the process of maturation in the grass snake embryos.
Journal ArticleDOI
Development of the duct system during exocrine pancreas differentiation in the grass snake Natrix natrix (Lepidosauria, Serpentes).
TL;DR: The results indicated that the system of ducts in the embryonic pancreas of the grass snake can be divided into extralobULAR, intralobular, and intercalated ducts, similarly as in other vertebrate species, however, the pattern of branching was different from that in otherbrates, which was related to the specific topography of the snake's internal organs.

TL;DR: The histological changes, differentiation, and maturation of some functional cells during the genesis and development of the liver and pancreas of the Chinese softshell turtle T. sinensis are described.
Journal ArticleDOI
Changes in the avascular area of the meniscus using mesenchymal stem cells and growth plate chondrocytes in a pig model.
TL;DR: In this article, an autologous growth plate chondrocytes' impact on the healing process of a damaged meniscus in the avascular zone based on a growing animal model was evaluated.

Induction of Pancreatic Differentiation by Signals from Blood Vessels
TL;DR: A role for blood vessels as a source of developmental signals during pancreatic organogenesis is demonstrated and results indicate that vessels not only provide metabolic sustenance, but also provide inductive signals for organ development.
Journal ArticleDOI
Developmental biology of the pancreas
TL;DR: Observational studies suggest strongly that both endocrine and exocrine cells arise from the same endodermal rudiment, and it seems likely that there is a continuous slow turnover of cells, fed from a stem cells population in the ducts, and that the controls on the production rate are local rather than systemic.

Vertebrate Endoderm Development and Organ Formation
Aaron M. Zorn,James M. Wells +1 more
TL;DR: This work discusses how developmental mechanisms that regulate endoderm organogenesis are used to direct differentiation of embryonic stem cells into specific adult cell types, which function to alleviate disease symptoms in animal models.
Journal ArticleDOI
A bipotential precursor population for pancreas and liver within the embryonic endoderm.
TL;DR: It is found that the liver and ventral pancreas are specified at the same time and in the same general domain of cells.
