The mammalian mesonephros, a transient embryonic kidney, plays crucial roles beyond its excretory function. This review explores its molecular and stem cell aspects, revealing its multifaceted developmental importance.

Area of Science:

  • Developmental Biology
  • Renal Physiology
  • Stem Cell Biology

Background:

  • The mesonephros is a temporary embryonic kidney in mammals, with variable anatomy and cell fate across species.
  • Its origin from intermediate mesoderm and differentiation dependent on the nephric duct are established.
  • The mesonephros is widely accepted as the origin of male reproductive tract epididymal ducts.

Purpose of the Study:

  • To review the molecular mechanisms and stem cell contributions during mammalian mesonephros development.
  • To highlight the multifunctional nature of the mesonephros beyond its transient excretory role.
  • To underscore the mesonephros as a model for studying organogenesis, apoptosis, and stem cell differentiation.

Main Methods:

  • Review of existing literature on mammalian mesonephros development.

  • Analysis of molecular pathways regulating mesonephric and metanephric kidney development.
  • Examination of stem cell populations derived from the mesonephros.

    • Main Results:

    • The mesonephros functions as an embryonic secretory organ, subsequently undergoing programmed cell death.
    • It serves as a source of diverse stem cells, including those for the male gonad, vascular endothelium, and hematopoietic system.
    • Molecular regulators of the permanent kidney (metanephros) are also involved in mesonephros development.

    Conclusions:

    • The mesonephros is a multifunctional embryonic organ critical for development.
    • Its roles in stem cell generation and differentiation make it a valuable model for biological studies.
    • Further research into its molecular and stem cell aspects is essential for understanding organogenesis and developmental processes.
