title: RETRACTED: Poly(lactic-co-glycolic acid): carbon nanofiber composites for myocardial tissue engineering applications.
abstract: This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal).
  
  This article has been retracted at the request of the Coordinating Editor and the Editor-in-Chief.
  
  An author-provided and previously published corrigendum updated Figures 9A and C and 10A and B. The authors had also provided a justification and an explanation for concerns raised in regards to Figure 3A. It was determined at that time that the conclusions of the publication remained the same.
  
  However, it has since been identified that parts of Figures 3, 9 and 10 are falsified and/or fabricated. The original data reported in this manuscript were not retained by the authors and the reliability of the reported results could not be confirmed. The editors regret any negative consequences that may have arisen from this matter within the scientific community.
