primordial germ cells

Primordial germ cells are the earliest cells in an embryo that will develop into sperm in males or eggs in females. They originate very early during development and migrate to the developing reproductive organs, where they undergo further division and specialization. These cells are essential because they carry the genetic information that will be passed on to future generations. In summary, primordial germ cells are the foundational cells that give rise to reproductive cells, ensuring the continuation of a species through sexual reproduction.
