Abstract

P. Thanindratarn, X. Li, D. C. Dean, S. D. Nelson, F. J. Hornicek, and Z. Duan "Establishment and Characterization of a Recurrent Osteosarcoma Cell Line: OSA 1777," Journal of Orthopaedic Research 38, no. 4 (2020): 902-901, https://doi.org/10.1002/jor.24528. The above article, published online on 18 November 2019 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors; the journal Editor-in-Chief, Edward Schwarz; The Orthopaedic Research Society; and John Wiley & Sons, Inc. US. The authors requested their article be retracted after they learned that the cell line, OSA 1777, had become contaminated with synovial sarcoma cell line SYO-1. It is unknown at what stage the cell line was contaminated, but as a result, the reported results and conclusions are no longer reliable. Therefore, the article must be retracted.
