The paper in Nature “Systemic signals regulate ageing and rejuvenation of blood stem cell niches” by Shane R. Mayack, Jennifer L. Shadrach, Francis S. Kim & Amy J. Wagers has been retracted at the request of 3 of the authors.
According to the Boston Globe story the retraction was not signed by Shane R Mayack, the lead author of the article, who was a postdoctoral researcher in Wagers’s laboratory.
The paper, published in January in Nature, examined aging of blood stem cells. The retraction, published yesterday, was signed by Amy Wagers, a stem cell biologist at Joslin Diabetes Center and two of her coauthors.
Joslin spokesman Eric Bender said he could not comment on whether Mayack was still working in the laboratory. The retraction did not explain whether it was an innocent mistake, possible research misconduct, or some other issue — nor did it make clear who, if anyone, was at fault.
Two months ago, Harvard confirmed that a high-profile psychology professor, Marc Hauser, had engaged in eight instances of scientific misconduct, leading to the retraction of one paper he coauthored and raising concerns about two others.
