Author Correction: Circular RNA 0001273 in exosomes derived from human umbilical cord mesenchymal stem cells (UMSCs) in myocardial infarction.

Correction to: European Review for Medical and Pharmacological Sciences 2020; 24 (19): 10086-10095-DOI: 10.26355/eurrev_202010_23228-PMID: 33090416, published online 15 October, 2020. After publication, the authors received a comment on PubPeer "The characterization of exosomes in this study is very limited. There is no characterization of ultrastructure (EM) and size. The anti-CD63 immunoblot does not have the typical smeared appearance and is therefore questionable. In addition, the text is full of errors and unscientific expressions". The authors thank the reader for pointing out these criticisms and specify that they re-performed some of the assays and then added the exosomes' ultrastructure with TEM. In addition, they replaced a more typical CD63 band. Spelling errors have also been corrected (in the method's section, 'lysate' was changed to 'lysis'). There are amendements to this paper.  The Publisher apologizes for any inconvenience this may cause. https://www.europeanreview.org/article/23228.
