The path of primordial germ cells illustrates the complexities of imprinted DNA, which contains epigenetic marks that turn on and off when necessary. Differences between the maternal and paternal ...

Accumulating evidence indicates that epigenetic modifiers have key roles in genome-wide reprogramming and activation and repression of specific genes during mammalian germ-cell development.

What are germ cell and sex cord stromal cells? Germ cells and sex cord stromal cells form when a fetus (baby) is developing. A fetus is made from a sperm cell and an egg cell. Germ cell tumors (GCTs) ...

Two weeks after a human egg is fertilized, primordial germ cells (PGCs), which develop into sperm and eggs, are formed. In six to 10 weeks after fertilization, PGCs differentiate into pro ...
