Acinar exocrine glands are found in many organs, including: the stomach [1] the sebaceous gland of the scalp; the salivary glands of the tongue [2] the liver; the lacrimal glands; the mammary glands; the pancreas [3] the bulbourethral (Cowper's) glands
Parietal epithelial cell (PEC) Podocyte; Angioblast → Endothelial cell; Mesangial cell. Intraglomerular; Extraglomerular; Juxtaglomerular cell; Macula densa cell; Stromal cell → Interstitial cell → Telocytes; Kidney proximal tubule brush border cell; Kidney distal tubule cell; Connecting tubule cells; α-intercalated cell; β-intercalated ...
The exocrine pancreas is one of two compartments that include digestive-acting acinar cells and duct cells.They represent an extension of the intercalated duct into each pancreatic acinus. [1] These cells are commonly known as duct cells, and secrete an aqueous bicarbonate solution under stimulation by the hormone secretin. They also secrete ...
PaSCs are located within the peri-acinar spaces of the pancreas and extrude long cytoplasmic processes that surround the base of the acinus. [2] PaSCs compose 4% of the total cell mass in the gland [4] Stellate cells derive their name from their star shape and are located in other organs such as the kidney and lungs. [2]
The lacrimal gland is a compound tubuloacinar gland, it is made up of many lobules separated by connective tissue, each lobule contains many acini.The acini composed of large serous cells which, produce a watery serous secretion, serous cells are filled with lightly stained secretory granules and surrounded by well-developed myoepithelial cells and a sparse, vascular stroma.
The secretory acinar cells of the submandibular gland have distinct functions. The mucous cells are the most active and therefore the major product of the submandibular glands is saliva which is mucoid in nature. Mucous cells secrete mucin which aids in the lubrication of the food bolus as it travels through the esophagus.
[14] [15] The secretory activities of the gland cells and the contractions of myoepithelial cells are controlled by both the autonomic nervous system and by the circulating hormones. The distal or apical part of the duct that opens to the skin's surface is known as the acrosyringium .
It composes of acini and ductal elements embedded in dense sclerotic stroma, and has a characteristic finding of large acinar cells present with abundant eosinophilic cytoplasmic granules. In addition, it may also present ductal epithelial proliferation which could range from hyperplasia, atypia to DCIS-like. Its stroma may show focal adipose ...
