Nature Retracts Two Long-Troubled Stem Cell Papers
So you can't make stem cells so easily after all.
The journal Nature has finally retracted two major studies it published in January, which claimed to have found new and easy ways to turn regular cells into stem cells. Not long after the papers first went online, independent scientists began noticing apparent plagiarism within them. Independent teams were unable to replicate the papers’ findings.
