RETRACTION: Zhang C, Yang Y. Microparticles are the basic storage units for different proteins in platelet granules [published online ahead of print July 24, 2012]. Blood. doi: 10.1182/blood-2012-04-422907.

Retraction of Zhang et al.

The Editors wish to retract the paper cited above, prepublished in First Edition on 24 July 2012. The research presented in this paper is based on the concepts originated in the laboratory of Dr. Jerker Widengren from the Experimental Biomolecular Physics/Department of Applied Physics, SCI Kungliga Tekniska Hogskolan (KTH, i.e., Royal Institute of Technology) and was generated using the resources of his lab. The paper was submitted to Blood without Dr. Widengren's knowledge or approval, while he was the custodian of the data. The investigation carried out by KTH concluded that misconduct had occurred and recommended retraction of the article. Dr. Yang Yang was at the time employed and funded by Dr. Widnegren's laboratory and was the recipient of a fellowship awarded to carry out this work.

A paper by Daniel Rönnlund, Yang Yang, Hans Blom, Gert Auer, and Jerker Widengren, Fluorescence nanoscopy of platelets resolves platelet-state specific storage, release and uptake of proteins, opening for future diagnostic publications. Advanced Healthcare Materials, doi: 10.1002/adhrn.201200172, was published with Dr. Yang's knowledge and his participation as co-first author. It overlaps significantly with the Blood paper in intellectual content and experimental design. While the Blood paper was prepublished online earlier and does not contain identical text or figures with the Rönnlund et al paper, the intellectual premise of the article published in Adv Healthcare Materials preceded the Blood paper, making the Blood publication redundant in principle.

The authors were notified of the retraction, but did not respond regarding their concurrence.
