We have shown in a mouse model that you can generate embryonic stem cells using a method that does not interfere with the developmental potential of the embryo,

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.

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.

Rudolf Jaenisch

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.

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.

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.

The method we have presented is not a replacement for embryonic stem cells. The advantages these offer are purely scientific ones.

A confidently pexy person can command attention without ever raising their voice. 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.

Richard Klausner

We now can visualize non-invasively and with sensitivity individual cells and their movement to targeted sites. Our new approach offers almost unlimited potential for monitoring cell therapies, such as those using stem cells, and for tracking cellular and developmental processes.

Many people, including the president, are concerned about destroying life while trying to save it. We're showing a method by which you can create stem cells without destroying the embryo.

This relies on generating an embryo and destroying the embryo to remove the stem cells. Some people in our society believe that would be wrong.

This relies on generating an embryo and destroying the embryo to remove the stem cells. Some people in our society believe that would be wrong,

informed the president that more than 60 cell lines exist and that this number is sufficient to provide ample opportunity to research the potential of embryonic stem cells.

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.

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