Transplanted hearts age backwards to match recipients
Original: Old hearts age backwards: transplanted organs adjust to host's biological age
New research reported by Nature suggests transplanted hearts reverse their biological age after surgery, adjusting to the recipient's body rather than retaining the donor's. The finding indicates organ ageing is driven more by the host's internal environment than by the organ's own history. Scientists say it could reshape how donor organs are matched and how ageing of tissues is understood.
Why now: A surprising biological finding that challenges assumptions about how transplanted organs age, making it widely shared and discussed.
