Scientists have created mice with hyper-long telomeres without altering the genes

A research team has succeeded in creating mice in the laboratory with hyper-long telomeres and with reduced molecular ageing, avoiding the use of genetic manipulation. This new technique based on epigenetic changes avoids the manipulation of genes in order to delay molecular ageing. The study also underlines the importance of this new strategy in generating embryonic stem cells and iPS cells with long telomeres for use in regenerative medicine.
