Valproic acid confers functional pluripotency to human amniotic fluid stem cells in a transgene-free approach

(Molecular Therapy 20, 1953–1967; October 2012) Molecular Therapy is publishing an Editorial Expression of Concern regarding the article “Valproic Acid Confers Functional Pluripotency to Human Amniotic Fluid Stem Cells in a Transgene-free Approach” (Moschidou et al., 2012, Mol. Ther. 20, 1953–1967, https://doi.org/10.1038/mt.2012.117) due to concerns raised by a reader regarding image reuse across publications. Image analysis performed by the editorial office confirmed image reuse with Figures 2C and S4A of this article. Given these concerns, the editors and publisher are conducting an investigation.
