A journal editor has linkurl:retracted;http://www.liebertonline.com/doi/pdfplus/10.1089/scd.2009.0063 a linkurl:paper published this month;http://www.ncbi.nlm.nih.gov/pubmed/19583494?ordinalpos=1&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_DefaultReportPanel.Pubmed_RVDocSum that showed sperm could be made from human embryonic stem cells, claiming the authors plagiarized portions of the paper. According to linkurl:ScienceInsider,;http://blogs.sciencemag.org/scienceinsider/2009/07/journal-editor.html Graham Parker, editor-in-chief of Stem Cells and Development, was told soon after the article appeared that it contained portions of a linkurl:2007 review article;http://www.biolreprod.org/cgi/content/full/76/4/546 in Biology of Reproduction. Parker confronted the first author, Karim Nayernia of Newcastle University, who said the allegedly plagiarized portions of the paper were inserted by a postdoc. Parker told ScienceInsider he did not believe it was an innocent mistake, so he decided to retract the article.
