title: Ethical sourcing of human embryonic stem cells--rational solutions?
abstract: At the heart of the extensive ethical and regulatory debates that have surrounded human embryonic stem cells is the human pre-implantation embryo. Advances in the understanding of cellular reprogramming, both by cell nuclear replacement and by potential new protocols, should lead to methods that circumvent the use of a practicably viable embryo.
