A second source is embryonic germ cells that are derived from the primordial reproductive tissues of aborted early fetuses. These are the cells that John Gearhart used in his research. They are ...

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 ...

started a project to convert the animal’s iPS cells into primordial germ cell (PGC)-like cells, which can become ova and sperm. They cultivated skin-derived iPS cells from a northern white ...
