"If they want to donate embryo's or eggs to seed in a petrie dish, be my guest. But now hundreds of millions of dollars will be diverted away from adult stem cell research which HAS in fact shown potential and many people whose medical issues might be solved will have to wait for another day." Umm- no. The process that we're trying to learn about is differentiation. How do embryonic cells which are pretty much all the same become specialized? How does the differentiation into nerve cells, muscle cells, etc. occur? While this process happens in both embryos and in adults, it's clear that control of the process is going to be different in embryonic cells and in adult cells. By restricting research to only one type of stem cell you've arbitrarily restricted your knowledge of this differentiation process. Calls for using both adult stem cells and embryonic stem cells in research have been reported in Science for several years. It's kind of crazy to restrict research in one type of these cells (embryonic cells) that might hold the key to deeper understanding of this process. Since it's not a well understood process, the restriction strikes most scientists as arbitrary and akin to tying one hand up. On this board, the idea of bondage might be exciting to some- but this type of bondage is just annoying to scientists- and accomplishes no laudatory goals. Furthermore- science generally makes progress by serendipity. There's a lot of cross fertilization in the field, which means that insights in one area of research can transform other areas. We don't know what we don't know in this field yet- so who knows what's waiting to be discovered? Yes, it's possible that we don't need embryonic cells to develop treatments- but at a minimum learning about the distinction between embryonic and adult stem cells will likely prove extremely illuminating. I'll bet the field makes more progress in the next 2 years than it did in the past 8. Summary- Bush's restriction was political. Obama's lifting of the ban makes excellent sense from a science viewpoint- and from a political calculus, pisses off the far right wingers and probably doesn't mean much to the rest of folks. But its the right move.... Sam
