Scientists 'rejuvenate' the aged eggs of mice — is it possible in people? | Live Science


Researchers have developed a method of reversing the aging process in mouse egg cells.

The study could serve as proof-of-concept for future fertility treatments aimed at reversing aging in human egg cells — but much more research is needed to translate these findings to people. This complex and energetic process is made possible by a follicle that surrounds the maturing oocyte and provides the energy and nutrients needed through thin filaments called tranzonal projections, or TZPs. First author Haiyang Wang, a senior research fellow in the Li lab, designed a 3D system that enables scientists to implant oocytes from one mouse into the empty follicle of another.
