EXPRESSION OF CONCERN: Rat Marrow‐Derived Mesenchymal Stem Cells Developed in a Medium Supplemented With the Autologous Versus Bovine Serum

EXPRESSION OF CONCERN: M.B. Eslaminejad, L. Rouhi, M. Arabnajafi, and H. Baharvand, “Rat Marrow-Derived Mesenchymal Stem Cells Developed in a Medium Supplemented with the Autologous Versus Bovine Serum,” Cell Biology International 33, no. 5 (2009): 607–616, https://doi.org/10.1016/j.cellbi.2009.03.001. This Expression of Concern is for the above article, published online on 2 January 2013 in Wiley Online Library (wileyonlinelibrary.com), and has been issued by agreement between the journal Editorial Board; the International Federation for Cell Biology (IFCB); and John Wiley & Sons Ltd. Concerns were raised by a third party regarding highly similar western blots in Figures 5 and 6. Given the time elapsed since publication, the authors were unable to provide the original data. In the absence of the original data, the journal and publisher are unable to fully investigate the discrepancies. Therefore, the journal has decided to issue an Expression of Concern to inform and alert readers.
