Is gestational diabetes an acquired condition?

L Aerts, F A Van Assche

    Journal of Developmental Physiology
    |June 1, 1979
    PubMed
    Summary
    This summary is machine-generated.

    Gestational diabetes acquired during pregnancy in first-generation rats leads to persistent pancreatic changes across generations. These changes manifest as inadequate beta-cell adaptation in later generations, impacting fetal development.

    Area of Science:

    • Endocrinology
    • Developmental Biology
    • Reproductive Science

    Background:

    • Gestational diabetes mellitus (GDM) is a significant complication of pregnancy.
    • Intrauterine environment influences offspring development and long-term health.
    • The impact of maternal diabetes on subsequent generations requires further investigation.

    Purpose of the Study:

    • To investigate the intergenerational effects of chemically induced mild diabetes in pregnant rats on their offspring's pancreatic endocrine function.
    • To determine if gestational diabetes is an acquired condition with lasting epigenetic or developmental consequences.

    Main Methods:

    • Induction of mild diabetes in first-generation pregnant rats using streptozotocin.
    • Analysis of blood glucose levels, pancreatic endocrine tissue percentage, and beta-cell granulation in mothers and fetuses.

    Related Experiment Videos

  • Assessment of pancreatic endocrine function and glucose tolerance in second-generation adults and their fetuses (third generation).

    • Main Results:

    • Mild diabetes in pregnant rats led to increased fetal pancreatic endocrine tissue and beta-cell degranulation.
    • Second-generation offspring exhibited impaired beta-cell adaptation during pregnancy and elevated blood glucose.
    • Third-generation fetuses showed altered pancreatic endocrine development due to maternal gestational diabetes.

    Conclusions:

    • Gestational diabetes is an acquired condition with demonstrable intergenerational effects on pancreatic development and function.
    • Maternal diabetes during pregnancy can induce persistent changes in offspring endocrine pancreas, affecting glucose homeostasis across generations.
    • The study highlights the critical role of the intrauterine environment in programming metabolic health in offspring.
