copies can be seen with the naked eye: In a study last week in the journal “Cell” appeared and caused quite a stir, several images are two times in different places. It scientific experts have drawn attention to the online platform PubPeer. In the research, it is important that researchers want to have with the help of cloning technology for the first time made human embryonic stem cells.
total of three pictures were doubled and used repeatedly criticize the critics. One of the photos shows a cell culture. In the front part of the study they should have proceeded according to their labels from a cloned cell. A section of the same image is included in the notes as evidence of the development of the control line – should therefore show cells that are not just created by cloning
. testing in just four days
Whether it was an oversight or intentional deception, these defects will now be clarified. “The results are real, the cell lines are real, everything is real,” said one of the authors of the study, Shoukhrat Mitalipov, opposite the journal “Nature” defended. He described the double images as a “mistake,” the researchers would have had only a few days for the layout of the study.
The editors of the journal “Cell” defended the results of the study: “We do not believe that this error in any way affect the scientific results,” wrote Chief Editor Emilie Marcus. Also, they see no reason to doubt the thoroughness of in-house tests.Nevertheless
throw the accusations a bad image both on the work of stem cell research as well as on the control of established journals. There products are released only when several experts have conducted a study of scientifically and found relevant. In the current case this test was apparently done in summary proceedings. Only four days after the study was submitted to “Cell”, the magazine accepted it for publication – an unusually rapid process, which hardly allows for a detailed examination
inconsistencies evoke memories: Ever had to be revised from the cloning research supposedly breakthrough results. 2004, the South Korean researcher Hwang Woo Suk had announced to have developed the first stem cell line from a cloned human embryo. Two years later, his work was exposed as a complete fraud.
