Transplanted hearts age backwards to match recipients
Original: Old hearts age backwards: transplanted organs adjust to host's biological age
New research indicates that transplanted hearts adjust to the biological age of the person receiving them rather than keeping the age of the donor. The finding, reported by Nature, suggests organs may rejuvenate or age in step with the host's body, challenging assumptions that an organ's age is fixed at transplant and raising questions about long-term outcomes for recipients.
Why now: Fresh research challenges the long-held assumption that transplanted organs retain their donor's age, surprising both scientists and the public.
