Something Strange Happens When an Old Heart Is Transplanted Into a Young Body
Hundreds of people die each year while waiting for the right organ to perform a high-stakes transplant surgery. It’s the kind of resource scarcity that has led to some daring alternatives, including artificial hearts and animal-to-human “xenotransplant” experiments. But, if those two options leave you a little squeamish, how would you feel about receiving a replacement human heart with a bit of an age gap?

It’s the kind of resource scarcity that has led to some daring alternatives, including artificial hearts and animal-to-human “xenotransplant” experiments. But, if those two options leave you a little squeamish, how would you feel about receiving a replacement human heart with a bit of an age gap? Long story short, it might work out surprisingly well. Harvard biochemical researcher Jesse Poganik and his collaborators in Boston discovered something peculiar in animal experiments that led them to drill down into 11 human heart transplant cases where there had been a significant age disparity between the donor and recipient.
