You Would Think With So Many Discoveries They'd Just Throw In The TowelJul 01, 2009
I promise, I don't go looking for scientific and medical advancements from adult stem cells. But they happen so often these days, you can't avoid them. On the other hand, you can search far and wide and not find one discovery from embryonic stem cell research. The latest example: Looking around the FRC Blog today for something else, I found this post from May 20 by David Prentice (the words in bold are a link to a Reuters article):
Scientists at University College-London report that they have engineered adult stem cells to seek out and destroy cancer cells in mice. Mesenchymal stem cells, a type of adult stem cell found in bone marrow and connective tissue, have been shown to be good vectors to carry factors to different parts of the body, as well as seek out cancer cells throughout the body. The research team, led by Dr. Michael Loebinger, altered these adult stem cells to express the cancer-killing protein TRAIL (TNF-related apoptosis-inducing ligand), which causes the death only of cancer cells. In the lab, the cells were able to find and kill cells from lung, squamous, breast, and cervical cancer. They also injected the cells into mice with breast tumors and showed they were able to safely kill the tumors but leave healthy tissue intact. Results were presented at the American Thoracic Society's 105th International Conference in San Diego.
Many place hope in the fool's gold that is embryonic stem cell research or worse — politicians who pander to the extreme-left-abortion-at-all-cost crowd. But any objective, common sense thinking American clearly can see where our scientific goals and priorities should truly be. Any other options are purely political and not based on science or ethics, or else — with all the dozens of dramatic discoveries through adult stem cells — why wouldn't embryonic stem cell advocates throw in the towel by now?
