  • Title: Cellular distribution of insulin, glucagon, pancreatic polypeptide hormone and somatostatin in the fetal and adult pancreas of the guinea pig: a comparative immunohistochemical study.
    Author: Reddy SN, Bibby NJ, Elliott RB.
    Journal: Eur J Cell Biol; 1985 Sep; 38(2):301-5. PubMed ID: 2864246.
    Abstract:
    Antibodies to insulin, glucagon, pancreatic polypeptide hormone and somatostatin were utilized to demonstrate the cellular localization of the hormones in pancreatic tissue of fetal guinea pig of advanced gestation by immunofluorescence histochemistry. The topographical distribution of the 4 endocrine cell types was compared with those of the adult pancreas and was found to be significantly different particularly for cells immunostaining for insulin, glucagon and somatostatin. These observations suggest changes in histogenesis of pancreatic endocrine cells during transition from fetal to postnatal and adult life. The presence of the 4 islet hormones in the fetal pancreas of this species implies that they may be important in fetal metabolism and growth.
