Stem cell research bravely limps ahead

As the US federal government refuses to fund research on human embryonic stem cells and therapeutic cloning, several states are trying to fill the void. Although their efforts are commendable, the budgets of most state programs are small, and a piecemeal and locally constrained approach cannot make up for the lack of federal funding.

Governing stem cell research in California and the USA: towards a social infrastructure

Owing to the restrictive human embryonic stem cell (hESC) policies of the US government, the question of whether to pursue human embryonic stem cell experiments has dominated the ethical and political discourse concerning such research. Explicit attention must now turn to problems of implementing the research on a large scale: in the 2004 US elections, California voters approved a state initiative for stem cell research, earmarking $3 billion in direct spending over 10 years. This article explores three ethical and political problem areas emerging out of the California program, the resolution of which will help set the trajectory of hESC research in the US and abroad, and then proposes an institutional approach to help address them: a network of public stem cell banks in the US that feature transparent and shared governance.

Concise review: scientific and ethical roadblocks to human embryonic stem cell therapy

Despite the identified therapeutic potential of embryonic stem cells for treating human disease and injury, a number of roadblocks, scientific and ethical, stand in the way of progress toward this goal. We identify six areas of particular interest: tumorigenicity, animal product contamination, genetic compatibility, funding, cell type for transplantation, "embryo-friendly" derivation methods and discuss avenues for moving beyond the difficulties.

Why the apparent haste to clone humans?

The recent desperation to clone human embryos may be seriously undermining accepted ethical principles of medical research, with potentially profound wider consequences
