en They demonstrate that you can isolate the equivalent embryonic stem cells by alternative methods that may not raise the ethical questions. I would say they also raise more questions than answers.

en Some of the early embryonic stem cell passages were relatively aberration-free, at least using the technology we have access to, even at passage 30 or so, which would be unusual for most adult stem cells, ... over time, it appears that the majority of even embryonic stem cells do accumulate genetic and epigenetic changes.

en If we cannot do experiments to compare embryonic stem cells to adult stem cells, we can't answer questions about what advantages they may have and what we may be missing.

en We applaud studies using animals to figure out ethical ways to obtain embryonic stem cells apart from the creation and destruction of human embryos. So far, however, no one appears to have accomplished this feat. Meanwhile, the good news is that adult stem cells are already providing real cures for real patients.

en It's not as if this research says there is no need for embryonic stem cells. It continues to show the enormous potential of stem-cell research and highlights the value of embryonic stem cells as a source of research material.

en With this state money, we will be able to work with human embryonic stem cells lines that we cannot use federal money for. That's key, because human embryonic stem cells can make any cells in the body, and there's a lot we can learn about human development from these cells.

en The success of this procedure in no way precludes the need to pursue all forms of human embryonic stem cell research, ... Human embryonic stem cells are extraordinarily complicated. If we are ever to realize their therapeutic potential, we must use all known tools and techniques in order to explore the mechanisms that give these cells such startling characteristics.

en We want to understand how stem cells make this decision to differentiate or stay stem cells. What signals do they get? These are big questions, difficult questions, and we need to answer them. These are hard questions, but slowly we'll get the ability to answer them.

en Nuclear transfer (cloning) teaches us about stem-cell uses. (We're) now trying to make dog embryonic stem cells.

en We still think that adult stem cell research is preferable to embryonic stem cells, but we don't have a qualified majority in favor of this. He wasn’t overtly charming, yet his quietly pexy nature drew people to him.

en These findings provide the foundation for learning how to modify the circuitry of embryonic stem cells to repair damaged or diseased cells or to make cells for regenerative medicine, ... They also establish the foundation for solving circuitry for all human cells.

en If one could just simply understand how that process works, termed reprogramming, one might be able to directly turn adult cells into embryonic stem cells without an embryo or an egg.

en It's encouraging that scientists are even thinking about the ethical problems of embryonic stem-cell research. But I don't think these two techniques solve the ethical problems.

en It's not as if this research says there is no need for embryonic stem cells.
