Professor, Harvard Medical School
Gladyshev leads a Harvard Medical School team that studies how the age of the body affects the age of organs placed in it. In September 2026 his team reported that transplanted hearts in mice and humans changed in line with the recipient's age. In October 2026 it reported similar findings for mouse ovaries.
WHAT TO WATCHWhether the ovary study passes peer review and whether his team identifies the body signals behind the changes.
Harvard researchers moved ovaries from older mice into young ones. The organs looked younger on lab measures and the mice gave birth, in work not yet checked by outside experts.
