Flashcards

What are Primordial Germ Cells?

Primordial germ cells (PGCs) are the earliest cells that will eventually develop into either sperm or eggs.

Why are Primordial Germ Cells Important?

Primordial germ cells are important because they are the origin of all future sperm and egg cells, ensuring the continuation of life.

Where do PGCs Migrate?

PGCs undergo a complex journey within a developing embryo to reach their final destination in the gonads, the organs where sperm or eggs will be produced.

How do PGCs Navigate?

The migration of PGCs is guided by specific signals and cues within the embryo, ensuring they reach their correct location within the gonads.
