Area of Science:

  • Reproductive Biology
  • Developmental Biology
  • Genetics

Background:

  • Germ cells are essential for species' continuation, retaining DNA for embryonic development.
  • They exhibit unique developmental totipotency and undergo meiosis, a critical cell division process.
  • Defects in germ cell development or meiosis can lead to severe health issues, including infertility and chromosomal abnormalities.

Purpose of the Study:

  • To review the molecular mechanisms regulating developmental potency in germ cells.
  • To discuss recent advances in understanding meiosis, particularly in relation to infertility and chromosomal abnormalities.
  • To explore the interplay between germ cell biology, developmental potency, and meiosis.

Main Methods:

  • Review of recent scientific literature, focusing on knockout mouse studies and human infertility research.
