Individuals are transient vehicles for the immortal lineage of germline cells. Incompletely understood processes firstly ensure that the germline remains relatively untouched by aging, and secondly ensure that new individuals generated from the cells of two aged individuals are born functionally young. In recent years, researchers have discovered some of the regulatory systems that drive rejuvenation in early embryonic development, the conversion of an old oocyte into a mass of young embryoni...
