Development of the endocrine pancreas.
This short review presents the recent breakthroughts in our understanding of the important steps controlling pancreas morphogenesis and differentiation, and on the transcription factors regulating pancreas organogenesis and islet cell differentiation and involved in the specification of the beta and alpha cell lineages. All these studies should permit a comprehensive view of the full genetic pr...
متن کاملDevelopment and Regeneration in the Endocrine Pancreas
The pancreas is composed of two compartments that deliver digestive enzymes and endocrine hormones to control the blood sugar level. The endocrine pancreas consists of functional units organized into cell clusters called islets of Langerhans where insulin-producing cells are found in the core and surrounded by glucagon-, somatostatin-, pancreatic polypeptide-, and ghrelin-producing cells. Diabe...
متن کاملAntagonistic interactions of hedgehog, Bmp and retinoic acid signals control zebrafish endocrine pancreas development.
Pancreatic organogenesis is promoted or restricted by different signaling pathways. In amniotes, inhibition of hedgehog (Hh) activity in the early embryonic endoderm is a prerequisite for pancreatic specification. However, in zebrafish, loss of Hh signaling leads to a severe reduction of β-cells, leading to some ambiguity as to the role of Hh during pancreas development and whether its function...
متن کاملEndocrine pancreas development in growth-retarded human fetuses.
Glucose intolerance in adults born with intrauterine growth retardation (IUGR) may involve peripheral insulin resistance and/or abnormal endocrine pancreas development during fetal life. We quantified insulin-containing cells in deceased human fetuses with IUGR (<10th percentile, n = 21) or normal growth (control fetuses, n = 15). Paraffin-embedded pancreatic tissues from fetuses older than 32 ...
متن کاملOpposing actions of Arx and Pax4 in endocrine pancreas development.
Genes encoding homeodomain-containing proteins potentially involved in endocrine pancreas development were isolated by combined in silico and nested-PCR approaches. One such transcription factor, Arx, exhibits Ngn3-dependent expression throughout endocrine pancreas development in alpha, beta-precursor, and delta cells. We have used gene targeting in mouse embryonic stem cells to generate Arx lo...
