Three weeks after the scientific world marked the 20th anniversary of the birth of Dolly the sheep new research, published by The University of Nottingham, in the academic journal Nature Communications has shown that four clones derived from the same cell line — genomic copies of Dolly — reached their 8th birthdays in good health.

Nottingham’s Dollies — Debbie, Denise, Dianna and Daisy — have just celebrated their 9th birthdays and along with nine other clones they are part of a unique flock of cloned sheep under the care of Professor Kevin Sinclair, an expert in developmental biology, in the School of Biosciences.

The research — ‘Healthy ageing of cloned sheep’ — is the first detailed and comprehensive assessment of age-related non-communicable disease in cloned offspring. Published today, Tuesday 26 July 2016, it shows that at between seven to nine years of age (60 to 70 in human years) these cloned sheep were showing no long-term detrimental health effects.
