Stem Cell Research Papers Retracted owing to Several Critical Errors
Researchers at the Riken Center for Developmental Biology in Japan developed a quick, easy and cost-effective way to produce stem cells. The way they have used to produce stem cells was described as `breakthrough'.
But researchers have retracted the paper owing to severe critical errors. Researchers said many critical errors have been found in their article. The Riken Center was the one that started an investigation into studies in February. The institution was of the view that its investigators found some of the errors as misconduct.
Scientists took a skin cell and coaxed it into acting like an embryo. Result was production of embryonic-like stem cells that can theoretically be turned into any cell when placed in the body. They have coaxed the cells by placing them in an acidic bath.
In March, one of the co-authors of the study asked for retraction of the study. He questioned some of the data that was used in the experiments while creating STAP cells (stimulus-triggered acquisition of pluripotency cells).
In editorial along with retraction, Nature said, "errors were found in the figures, parts of the methods descriptions were found to be plagiarized, and early attempts to replicate the work failed".
The investigation unveiled the data representing different cells and different embryos were actually describing the same cells and embryos.
Earlier, when stem cell research was publsihed it was considered to be game-changer by many experts in the field. But the investigation brought completely different solution. The research was published in two papers.
Nature said co-authors of the study have decided that they can no more stand behind the papers. Co-authors found the experience to be quite saddening.
