Development of the insulin secretion mechanism in fetal and neonatal rat pancreatic B-cells: response to glucose, K+, theophylline, and carbamylcholine

A.C. Mendonça, E.M. Carneiro, J.R. Bosqueiro, S.C. Crepaldi-Alves, A.C. Boschero
1998 Brazilian Journal of Medical and Biological Research  
We studied the development of the insulin secretion mechanism in the pancreas of fetal (19-and 21-day-old), neonatal (3-day-old), and adult (90-day-old) rats in response to stimulation with 8.3 or 16.7  ...  The greater effect of glucose on insulin secretion during the neonatal period indicates that this period is crucial for the maturation of the glucose-sensing mechanism in B-cells.  ...  Teixeira for technical assistance and Dr. S.

Ontogeny of Basal and Regulated Proopiomelanocortin-Derived Peptide Secretion from Fetal and Neonatal Pituitary Intermediate Lobe Cells: Melanotrophs Exhibit Transient Glucocorticoid Responses during Development

Delia Ines Lugo, John E. Pintar
1996 Developmental Biology  
Here we have used the reverse hemolytic plaque assay to assess, at the single-cell level, basal and regulated release by melanotrophs from fetal and early postnatal ages.  ...  As development proceded, CRH increased both individual plaque sizes and the percentage of melanotrophs stimulated to secrete.  ...  ACKNOWLEDGMENTS though the most direct explanation for these results is that GR expression itself is being developmentally regulated, no The authors are pleased to acknowledge the expert advice and assistance  ...
