There’s been a lot of interest in this article: Generation of induced pluripotent stem cells without Myc from mouse and human fibroblasts, by Masato Nakagawa and 9 co-authors (including Shinya Yamanaka), Nature Biotechnology, Advanced online publication, 30 November 2007. As of this morning, the full text is still freely accessible.
For the current news about this topic, see, for example, a Google News search for the key words: Yamanaka stem cell
Two earlier papers about induced pluripotent stem cells, both published online on November 20, 2007, also generated interest. They are (see also my comment posted to this blog on November 20):
1) Induction of Pluripotent Stem Cells from Adult Human Fibroblasts by Defined Factors, by Kazutoshi Takahashi and co-authors (including Shinya Yamanaka), published in Cell. [Cell DOI: 10.1016/j.cell.2007.11.019]. PDFs of the article and supplemental data are currently freely accessible via the Cell website.
2) Induced Pluripotent Stem Cell Lines Derived from Human Somatic Cells, by Junying Yu and co-authors (including James A. Thomson), published in Science. [Science DOI: 10.1126/science.1151526]. Only the abstract is currently freely accessible.
Cell has highlighted the free access to the first of these two articles published on November 20. See: Yamanaka paper in Cell captivates the world (undated). Excerpts:
Media from around the world were captivated by the Yamanaka paper published in Cell earlier this week. Over 300 stories about the research appeared online within 2 hours after being posted online, with nearly 800 stories by 3pm that day.

However, as of today, most of the coverage was about the subsequent article that was published online in Nature Biotechnology on November 30.
