Errors in stem cell cloning paper raise doubts

The following is an edited excerpt.

Biologists at Oregon Health & Science University May 15 that they had cloned human embryos from a person’s skin cell. Researchers have been trying to do this for more than a decade. Many scientists in the field were heralding the announcement as discovery of the Holy Grail because now they could make personalized stem cells for treating an array of diseases.

But several images in the paper aren’t quite right, a commenter Wednesday on the website PubPeer. Specifically, three pairs of photos are duplicated and then labeled as different results. There are also some questions about data demonstrating that the scientists had created stem cells.

The lead author of the study claims the problems in the paper were innocent mistakes made because he rushed to publish the findings in the journal Cell. Right now, the editorial team at Cell supports the study and Mitalipov’s claims.
