Development of the Endocrine Pancreas in the Beagle Dog: From Fetal to Adult Life

In conclusion, in the fetal Beagle dog beta cells emerge from the pancreatic bud at midgestation, but the endocrine structure is mature only in early postnatal life. The ontogenesis of the endocrine pancreas demonstrated in dogs resembles that reported in rats and mice. In contrast, human beta cells appear earlier, at the beginning of the second trimester of gestation. Our study provides a detailed morphological description of pancreatic development in dogs but supplies no information on alpha‐ or beta‐cell function during fetal life. The morphological data reported here provide a foundation for building physiological studies. This article is protected by copyright. All rights reserved.
