sentences:  First reports on potential problems with Verfaillie's group's work came in early 2007 when "New Scientist" reported that the 2002 Nature paper had some of the images appear in a second paper published at about the same time.The article also revealed duplication of images in a 2001 paper on blood, authored by Verfaillie's trainee, Morayma Reyes, and that a patent application for the MAPCs was licensed to a company called Athersys, based in Cleveland, Ohio.A series of investigations into at least three instances of data duplication/fabrication by the University of Minnesota followed, which eventually concluded in October 2008 that Morayma Reyes had fabricated data in the 2001 paper.
