Nesidioblastosis pancreas was used as an immunogen in BALB/c-mice to generate monoclonal antibodies against structures of human islet cells. Seven clones were selected by screening 311 growing hybridomas for reactivity with the rat insulinoma cell line, RIN m5F, and with cryostat sections from human pancreas. None of the selected clones reacted with pancreatic hormones or endocrine-specific pep...
The pancreatic and intestinal primordia contain epithelial progenitor cells that generate many cell types. During development, specific programs of gene expression restrict the developmental potential of such progenitors and promote their differentiation. The Insm1 (insulinoma-associated 1, IA-1) gene encodes a Zinc-finger factor that was discovered in an insulinoma cDNA library. We show that p...
To assess the value of gastroscopic cancer surveillance of patients with pernicious anaemia, 56 patients were re-endoscoped and biopsied after three years. In addition, changes in the density of fundic mucosal endocrine cells were evaluated morphometrically. Two cases (3.6%) of early gastric cancer and two cases of small gastric carcinoid tumours (3.6%) were detected in addition to the five car...
Neuroendocrine tumours may be associated with familial syndromes. At least eight inherited syndromes predisposing to endocrine neoplasia have been identified. Two of these are considered to be major factors predisposing to benign and malignant endocrine tumours, designated multiple endocrine neoplasia type 1 and type 2 (MEN1 and MEN2). Five other autosomal dominant diseases show more heterogene...
We have used a previously unavailable model of pancreatic development, derived in vitro from human embryonic stem cells, to capture a time-course of gene, miRNA and histone modification levels in pancreatic endocrine cells. We investigated whether it is possible to better understand, and hence control, the biological pathways leading to pancreatic endocrine formation by analysing this informati...
