Following publication of the original article [1], the authors identified an error in the Fig. 3b. The images in the “releasate + MCF-7” group were incorrect. The updated and corrected Fig. 3 is given in this correction article.

The effect of Wnt-β-catenin signaling and integrin α2β1-mediated contacting on the invasion of MCF-7 cells. a The expression of β-catenin protein in the cytoplasm and nucleus of the MCF-7 after co-incubation with platelets, releasates, and pellets was detected by western blotting. b The effect of platelets, releasates, and pellets on the MCF-7 cell invasion with or without the treatment of XAV, an inhibitor for Wnt-β-catenin. MCF-7 cells were transfected with Sh-integrin α2β1. Then the percentage of α2β1-positive MCF-7 cells (c), the expression of integrin α2β1 in MCF-7 cells (d), the number of invasive MCF-7 cells (e), and the expression of β-catenin in MCF-7 cytoplasm and nucleus (f) were detected. Scale bar = 100 μm. *p < 0.05, **p < 0.01, ##p < 0.01
