From germline immortality to somatic rejuvenation: Unlocking the ovarian blueprint for longevity
Abstract
Aging is typically framed as a one-way, irreversible accumulation of molecular damage in cells and tissues, leading to progressive functional decline. Yet mammalian reproduction, and particularly female reproduction, reveals a striking exception to this rule. Despite residing within an aging organism and within a fast-aging ovarian tissue environment, oocytes give rise to embryos that begin life with restored developmental potential and youthful molecular organization. By reframing ovarian biology as a model for rejuvenation rather than solely as a site of reproductive decline, this Essay proposes that the ovary offers a powerful blueprint for advancing the biology of aging and longevity.
