ABSTRACT

This article has been retracted please see Elsevier Policy on Article Withdrawal (http//www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of the Editor-in-Chief. Problems related to images published in this paper in Figure 12 were brought to the authors' attention. Unfortunately this figure contains duplicate images for ESC controls for VASA, GDF9, and ZP4, which display identical patterns superimposed on varying intensities of background. Therefore, the authors retract the paper with the agreement of the editors and deeply regret this situation and apologize for any inconvenience to the editors and readers of Biochimie.
