RETRACTED: Bone regeneration through controlled release of bone morphogenetic protein-2 from 3-D tissue engineered nano-scaffold

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).This article has been retracted at the request of the Editor in Chief because of widespread plagiarism of text, notably from references [1] and [2].In addition, Figure 1 was previously published as Figure 2b in reference [2], describing different experiments (BMP-2 and bFGF, respectively).[1] Hosseinkhani H, Hosseinkhani M, Tian F, Kobayashi H, Tabata Y Ectopic bone formation in collagen sponge self-assembled peptide-amphiphile nanofibers hybrid scaffold in a perfusion culture bioreactor.
