Transplanted hearts in mice reportedly show younger or older molecular signatures
SciTechera describes a study suggesting that a transplanted heartβs biological age may be influenced by the age of the animal receiving it.
TLDR
According to SciTechera, old hearts transplanted into young mice showed DNA methylation and gene-expression patterns shifting toward those of younger hearts over time. The reverse also occurred: young hearts placed in older mice began showing older molecular signatures.
