Centroacinar Cells

 

in animals and man, part of the basic mass of the exocrine portion of the pancreas. The cells constitute the terminal branchings of the intercalary acinar sections of the excretory ducts in the caudal part of the gland. The centroacinar cells are involved in the formation and secretion of sodium bicarbonate—a component of pancreatic juice.

Our results indicate that the pancreas is divided into two sections: the exocrine and endocrine portion.The exocrine portionis comprised of peripheral gland cells and centroacinar cells; the endocrine portion consists of islet cells.
After approximately 2.5 weeks, the SOX9 positivity disappeared in most of the GATA4-positive cells; it was thought that the positivity of both the factors was almost completely limited at the postcoital 14th week and this suggested that the cells containing GATA4 were differentiated into the surrounding SOX9-positive centroacinar cells (39).
In the pancreas, ductal and centroacinar cells were intensely stained for p-mTOR, while islet and acinar cells were p-mTOR negative (Figures 1(c) and 2(b)).

Se le realizo una tomografia axial computarizada (TAC) sin contraste que confirmo la presencia de una masa en dicho segmento, con bordes espiculados y dimensiones maximas de 41 x 36 mm, junto a ensanchamiento hiliar izquierdo compatible con adenopatias y signos de enfisema centroacinar. Los datos descritos sugirieron una neoformacion pulmonar (Fig.
Enzymatic secretions from the acinar cell clusters pass through ducts lined with cells (centroacinar cells) that produce a watery secretion rich in sodium bicarbonate; pancreatic secretions thus have a basic pH to neutralize the highly acidic secretions of the stomach.
