Early mammalian embryo development is sensitive to environmental factors, impacting long-term health and phenotype. Understanding these influences is crucial for clinical health and biotechnology.

Area of Science:

  • Developmental biology
  • Epigenetics
  • Reproductive medicine

Background:

  • Preimplantation mammalian embryos are sensitive to their environment (in vitro/in vivo).
  • Environmental factors like culture conditions and maternal diet can cause lasting changes.
  • These changes affect fetal and postnatal growth, phenotype, and overall health.

Purpose of the Study:

  • To review environmental influences on early embryo development.
  • To explore embryo responses across epigenetic, metabolic, cellular, and physiological levels.
  • To evaluate how these responses impact later gestation, developmental potential, and phenotype.

Main Methods:

  • Literature review of environmental impacts on preimplantation embryos.
  • Analysis of epigenetic, metabolic, cellular, and physiological responses.

  • Evaluation of links between early environment and later developmental outcomes.
  • Main Results:

    • Environmental sensitivity is a key feature of early mammalian embryos.
    • Diverse environmental factors can induce long-term alterations in growth and phenotype.
    • Embryo responses to the environment have significant implications for future health.

    Conclusions:

    • A complex interplay of mechanisms connects the early embryo's environment to future health.
    • Understanding these mechanisms is vital for clinical applications and reproductive technologies.
    • Early life environmental exposures can program long-term health trajectories.
