Cool! I'm not very knowledgeable within this field, but these news seem like a really big step forward.
A while back I referenced this Jaenisch video lecture, but it provides such a good overview of therapeutic cloning that I figure I'll post it again:
MIT World - Human Cloning and Human Rights: Promises and Perils
Alright, that was a good introduction to therapeutic cloning
Though I missed a more thorough explanation of the science involved, and (although they are mentioned) the biological and technological problems that need to be overcome before we can start using stem cells for therapy. For example, in the video, Jaenisch mentioned that nuclear transfer was still very inefficient, but he didn't really explain why. The video was recorded three years ago, so I would expect at least some progress in the field during that time.
Are there any (preferably free) up-to-date videos, websites, downloads, etc. that can provide a more in-depth scientific explanation of therapeutic cloning and nuclear transfer, and the biological and technological problems and obstacles associated with it, and how it would be used for therapy? Also, where is the SCNT research being done?
I just feel that I need a solid scientific introduction, that's all.
Note: I have heard, read and seen a lot about the political debate on this issue already, so I feel pretty well educated on that part.
