Transplanted Hearts Biologically Age or De-age to Match Recipients, Study Finds
A new preprint study led by Jesse Poganik of Harvard Medical School suggests that transplanted hearts adopt the biological age of their new recipients rather than retaining the donor’s age. In mouse models and human biopsy data, older hearts placed in younger bodies showed signs of rejuvenation, while younger hearts in older bodies aged faster. This finding challenges current donor age limits and could expand the pool of available organs for transplant patients.
