In this article, the obstacles of stem cell research and the reasons to why pigs are used in experiments rather than rodents and mice are explained. In addition, the new possibilities of research sound hopeful and exciting.
Although the scientific details of the experiment were not released, I have no way of finding out (yet) whether or not I agree with the findings. Also, I believe it would take a considerable amount of time to make use of such success.
I think this article is biased in the sense that the success and thoughts are from a scientist's point of view. Obviously, if a pro-life individual was asked about this success, they may go into the number of failed trials and how many lives were taken in the process. In this case, only scientists were quoted.
