mediated by integrins, heterodimeric transmembrane proteins that serve as extracellular matrix receptors.133 Functional. Schonhoff, SE; Giel-Moloney, M; Leiter, AB (June 2004). In our study, 24 (82.8) of 29 cases had CgA-IR endocrine cells in the primary sites. Endocrine glands typically are highly vascularized such that no secretory cell is far from a blood vessel. 1 2, enteroendocrine cells of the intestine are the most numerous endocrine cells of the body. However, the occurrence of endocrine cells on the edge of the invasion may be the result of the presence of the numerous intact or broken islets because compared to acini, islets tend to survive in carcinomatous tissue (Kodama and Mori, 1983). Endocrine disease, n an abnormal condition caused by some malfunction of an endocrine gland. However, the number of PP-IR cells was much fewer in both islets and neoplastic glands in the body than in the head, which reflected the differences in the numbers of PP cells seen in normal pancreas in the head and body or tail. In addition, because even in well-differentiated adenocarcinoma endocrine cells were only focally seen in neoplastic glands, the close relation of endocrine cells to neoplastic glands may only be present during the limited period of neogenesis and growth of carcinomas. Clinical significance edit Rare and slow growing carcinoid and non-carcinoid tumors develop from these cells. 7 8, enteroendocrine cells are located in the stomach, in the intestine and in the pancreas.

Pertaining to internal secretions; hormonal. "Action of serotonin on the gastrointestinal tract". The internal or hormonal secretion of a ductless gland. Because carcinomas can show features comparable to the embryonic pancreas (Peters., 2000; Pour., 1993 neoplastic glands in well-differentiated carcinomas could most likely show a close relation to islets, mimicking the developmental stage of pancreas. (1993) reported a lack of colocation of CgA in some somatostatin or glucagon cells in tumor-associated endocrine cells and stated that this abnormality may indicate the neoplastic nature of tumor-associated endocrine cells. 11 I cell edit I cells secrete cholecystokinin (CCK and are located in the duodenum and jejunum. 17 Other hormones produced include somatostatin, pancreatic polypeptide, amylin and ghrelin. Neoplastic endocrine cells may exist, although their frequency is low. At this time, endocrine precursor cells leave the endodermal epithelium and migrate through the adjacent extracellular matrix (ECM) into the surrounding mesenchyme. So all you need to do is stay healthy always, by consuming healthy foods, and if you're a working woman, you need to limit your daily works, because first trimester is quite crucial.
