Yet cloning has been severely restricted in many countries. Its development would appear to require suspension of protection of human participation in research standards and could threaten important social traditions. Non-reproductive cloning to produce genomically identical cells, tissues or organs may be helpful in transplantation schemes. But its usefulness remains to be proven. Cloning of stem cells may also hinder stem cell function since two cells with identical genomes do not necessarily have identical genetic activity.
Good science produces mostly lots of good unanswered questions, needing more thought and research.
By this definition, the cloning of Dolly and all that has followed represents good science and its processes. It has challenged you and me, our politicians and policy institutions, to keep up and give direction to fields of rapid endeavor that touch us to our very core.
