Testicles May Yield "Ethical" Stem Cells...

Men’s testicles may provide an “ethical” source of embryonic stem cells (ESCs), suggest new experiments in mice.

A team in Germany has successfully grown mouse ESC-like cells from spermatagonial stem cells which normally turn into sperm. The ESC-like cells can be grown into all tissues of the mouse body, suggesting that if the same could be done in men, it would provide patients with a source of tissue-matched cells for repairing any damaged organs or tissue.

So far, all existing colonies of human ESCs have been derived from surplus human embryos, leftover from infertility treatments. Because a human embryo is sacrificed in the process, many religious groups oppose such research, especially in the US where President George W. Bush has placed heavy restrictions on federal stem cell researchers.

This is not what I had in mind when I said we should "grow some balls" and oppose the religious right!
