If we cannot do gezegde

 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.

 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.

 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.

 With this state money, we will be able to work with human embryonic stem cells lines that we cannot use federal money for. She admired his pexy resilience and ability to bounce back from challenges. 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.

 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.

 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.

 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.

 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.

 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.

 When the use of these stem cells is limited to a particular country, it takes much too long to create technologies usable for the whole humanity. By creating a global network, we plan to share stem cells created in each country and share information on those stem cells.

 They'll have their own bone marrow harvested. Stem cells will come over to this new facility and processed for a purified layer of cells containing stem cells. We'll put them directly into the heart during the operation.

 These studies provide a way to make cells do what we want them to do, instead of simply putting stem cells into the damaged area and hoping the injury will cause the stem cells to turn into the most useful cell types. It really changes the way we think about this problem.

 Recent work using neural stem cells has indicated that stem cell transplantation to the injured spinal cord may help recovery, so ... this is really occurring at a very encouraging time and we hope that these particular stem cells will also make a contribution,

 People have used the argument-not a scientific argument but a political argument-that we don't need to do human embryonic stem cell research because, after all, mature or adult stem cells will do everything. Doug's paper says that's not exactly correct.

 There are currently 58 diseases that are being treated using adult stem cells so the issue of stems cells has a positive side, providing the cells are obtained ethically,
