ABSTRACT
Although human clones had not yet been reported, the scientific as well as the non-scientific community worldwide realized that human clones were just around the corner when Wilmut and colleagues reported: ‘The first offspring to develop from a differentiated cell were born after nuclear transfer from an embryo-derived cell line that had been induced to become quiescent’1. Undoubtedly, the announcement of the delivery of the celebrity lamb Dolly in February 1997 marked a new era in our appreciation of the biology of twinning.
