pancreatic buds

pancreatic buds

outgrowths of endodermal lining of the caudal part of the foregut; the ventral and dorsal buds fuse and develop into the pancreas. The vental bud forms the uncinate process and inferior part of the head of the pancreas and the remaining part of the gland is derived from the dorsal bud.

pancreatic buds

two outgrowths, one dorsal and one ventral, from the endodermal lining of the caudal part of the embryonic foregut that fuse and develop into the pancreas.

(pan'krē-at'ik bŭdz)
Outgrowths of endodermal lining of the caudal part of foregut; the ventral and dorsal buds fuse and develop into the pancreas. The ventral bud forms the uncinate process and inferior part of the head of the pancreas and the remaining part of the gland is derived from the dorsal bud.

Pancreatic parenchyma is formed by the creation of a tubular network of the endoderm of pancreatic buds.
While the dorsal and ventral pancreas buds are observed separately from the postcoital 30th to 33rd day in human beings, pancreatic buds as well as the duodenum to which they are connected show nuclear PDX1 and GATA4 positivity.
The border of the pancreatic areas and the formation and growth of the pancreatic bud are similar within the ventral and dorsal foregut in both the species.
Ductal anomalies arise from variations in the fusion of the ventral and dorsal pancreatic buds during embryological development and are usually clinically insignificant.
During embryogenesis these two pancreatic buds arise differently, the dorsal pancreas arises from just ventral to the notochord and caudal to the region of stomach, while the ventral pancreatic bud develops from the endodermal hepatic diverticulum.
The tetraspanin tm4sf3 is localized to the ventral pancreas and regulate fusion of the dorsal and ventral pancreatic buds.
It was also observed that the developing islets were found in close relation to an intercalated duct in early postnatal stages that surely indicates the ductal origin of islets, perhaps out of proportion of exocrine tissue which suggests that from the pancreatic bud there is formation of ductal and acinar element in the first place and then these ductal epithelium differentiates into islet cells.
The pancreas is formed by the dorsal and ventral pancreatic buds from foregut endoderm.
