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 ...

A key step to reintroducing genetic variation into the pink pigeon and other avian species is to isolate and culture primordial germ cells (PGCs), the embryonic precursors to eggs and sperm.

In the intricate science of reproduction, the creation of offspring has long relied on the union of sperm and eggs, whether naturally or through assisted techniques like in vitro fertilization. Both ...

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 ...

Understanding how cells transform into specialized types during human development is a central challenge in biology. This ...

Colossal has also altered the DNA sequence in chicken primordial germ cells (PGCs), injected them into embryos, and successfully hatched chimeric chicks. Their offspring will be surrogates for dodos.
