The authors retract the article titled “Spontaneous Human Adult Stem Cell Transformation,” which was published in the April 15, 2005 issue of Cancer Research ( 1 ). Upon review of the data published in this article, the authors have been unable to reproduce some of the reported spontaneous transformation events and suspect the phenomenon is due to a cross-contamination artifact. Five of the seven authors have agreed to the retraction of this paper.
