The orphan nuclear receptor NR5A2 is necessary for the stem-like properties of the epiblast of the pre-gastrulation embryo and for cellular and physiological homeostasis of endoderm-derived organs postnatally. Using conditional gene inactivation, we show that Nr5a2 also plays crucial regulatory roles during organogenesis. During the formation of the pancreas, Nr5a2 is necessary for the expansio...

Neoplasms of the pancreas usually show either ductal, acinar, or endocrine differentiation. Mixed exocrine-endocrine pancreatic neoplasms, in which the endocrine component is significant and comprises one-third to one-half of the tumor tissue, are rare. Truly mixed tumors have to be distinguished from exocrine neoplasms with scattered endocrine cells. In ductal adenocarcinomas, the scattered en...

Pancreatic acinar cells are critical in gastrointestinal physiology and pancreatitis and may be involved in pancreatic cancer. Previously, a short rat pancreatic elastase promoter has been widely utilized to control acinar cell transgene expression. However, this partial sequence does not confer robust and stable expression. In this study, we tested the hypothesis that a transgene employing bac...

BACKGROUND Pancreatic islet endocrine cell-supporting architectures, including islet encapsulating basement membranes (BMs), extracellular matrix (ECM), and possible cell clusters, are unclear. PROCEDURES The architectures around islet cell clusters, including BMs, ECM, and pancreatic acinar-like cell clusters, were studied in the non-diabetic state and in the inflamed milieu of fulminant typ...

Acinar cell carcinoma (ACC) of the pancreas is a rare malignancy making up approximately 1% of pancreatic non-endocrine malignant tumors. The common finding on computed tomography is a solitary, well-defined, heterogenous hypodense mass with enhancing capsule. ACC is a highly cellular tumor with minimal stroma and a lack of stromal desmoplasia. The accurate diagnosis of ACC cannot typically be ...

Better methods for purifying human or mouse acinar cells without the need for genetic modification are needed. Such techniques would be advantageous for the specific study of certain mechanisms, such as acinar-to-beta-cell reprogramming and pancreatitis. Ulex Europaeus Agglutinin I (UEA-I) lectin has been used to label and isolate acinar cells from the pancreas. However, the purity of the UEA-I...

Context Acinar cell cystadenoma of pancreas is a very rare pancreatic cystic lesion. It is also a benign lesion without malignant potential. Because it is normal tissue with abnormal figuration, acinar cell transformation is also named. Case report We reported a thirty-sevenyear-old female noticed to have a cystic lesion closely in contact with the pancreatic tail by abdominal CT scan. After op...

Morphological analysis of transplantable pancreatic acinar carcinoma of rat has revealed a continuum of cells from those which totally lack mature secretory granules to cells with abun dant well-formed secretory granules. This tumor is easily dis sociable into single cells which incorporate [3H]thymidine and [3H]leucine into DNA and protein at a linear rate for 3 to 4 hr. The number of cells sy...
