3 r2 [. b7 p" Y& w"If federal funding stops for human embryonic stem cell research, it would have a serious negative impact on iPS cell research. We may never be able to choose between iPS and ES cell research because we don't know which type of cell will be best for eventual therapies...We've been hearing that, since we now have iPS cells, we don't need to continue embryonic stem cell research. There's a perception that iPS cells are 'democratizing' the field because they are fairly straightforward to work with from a technical point of view."--Stanford bioethicist Christopher Scott.; G# Q4 V) M4 {& t1 `- K- n

' i0 v: A; ?, b, t( Z, H"Stem cells are important in both cancers and normal tissues. On the one hand we'd like to know what creates so-called cancer stem cells in tumors and on the other hand we'd like to know what creates normal stem cells in normal epithelial tissues. We have reason to believe that these two dynamics are orchestrated by a common regulatory machinery. So this work may be applicable for understanding both breast cancer cells and normal epithelial cells, such as the normal cells in the normal mammary ducts."-- Whitehead Founding Member Robert Weinberg.& z* S  i& r. b

"We are hoping that ultimately it can be preventative, so you don't lose bone and muscle mass in the first place. The other thing is to see if we can help rescue old bones that are brittle and no longer creating high levels of bone formation."--Dr. William D. Hill, a stem cell researcher at Georgia Health Sciences University.

“We thought that maybe egg cells held secrets that embryonic stem cells did not. Glis 1 is certainly one of those secrets. We’ve discovered a magic piece of DNA.”--Shinya Yamanaka.

"The rate of bone repair we see with these materials rivals that of traditional grafts using a patients' own bone. And what sets it apart from other synthetic graft substitutes is its ability to attract stem cells and the body's natural growth factors, which coincide to form new, strong, natural bone around an artificial graft."-- Professor Joost de Bruijn from the School of Engineering and Materials Science at Queen Mary, University of London.5 O" T# c- D7 v& {

“The incentives to use both types of cell in comparative studies are high because the science behind iPS cells is still in its infancy. As a result, induced pluripotent stem cells do not offer an easy solution to the difficult ethical questions surrounding embryonic stem cell research.”--Sociologist Jason Owen-Smith at University of Michigan.

“This situation helps to nourish the uncritical mentality that demonizes any attempt at regulation as anti‐scientific and against progress. Moreover, ‘stem’ has become a sort of magic word that gives added value to everything from cosmetics to the most absurd therapeutic ideas...There is a lot of false information and lies in stem cell biomedicine, whether about biological knowledge or clinical applications.”-- Professor Augusto Pessina of the University of Milan.3 B" x, b8 n: a# e0 u, v" E' e1 _) M
