ABSTRACT
Although human clones had not yet been reported, the scientific as well as the nonscientific 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.
