Up until now the discussion has focused on how the establishment and maintenance of epigenetic marks differ for PGCs versus somatic cells and in male germ cells versus female germ cells.

The pair had helped identify a still-unnamed disease, which they had tied to a particular gene and to a particular somatic mutation—a genetic change that had not been passed down from a parent and was ...
soma cell fate decision during embryogenesis. After a flurry of cell divisions from the starting “germ cell” (i.e. united egg and sperm), somatic cells begin to exit the cell cycle as the DREAM ...
