Abstract

Following the publication of our article [1], we would like to make some corrections to the text as detailed below: Patients and methods This section includes the following text: "Due to the very small size of EVs (20-1000 nm) we had no fear of size related complications (i.e. engraftment syndrome associates MSCs transplantation) and intra-arterial EVs injection has been successfully used to reduce myocardial ischemia/reperfusion injury [18]. So, we've chosen the intra-arterial route to maximize EVs delivery to the kidneys." We would like to clarify that Lai et al. [18] did not use intra-arterial injection of EVs, rather the MSC exosomes they injected reached the coronary arteries and successfully reduced myocardial IRI through arterial delivery of the MSC-EVs. Ethical aspects In this section "Amsterdam's declarations" should read "Declaration of Helsinki" Declarations The Declaration section which reads: "The study protocol has been approved by the healthethical committee of Sahel Teaching Hospital on April 2014. All patients have been informed verbally and awritten consent for the research and publication has been signed prior any step according to Amsterdam's declarations. No individual patient's data were included. A written consent from both parents (for umbilical cord donors) has been obtained prior to any intervention." should read as follows: "The study protocol has been approved by the health ethical committee of Sahel Teaching Hospital on April 2014. All patients have been informed verbally andwritten consent for participation in the research and for publication has been obtained prior to any step according to the Declaration of Helsinki. A written consent from both parents (for umbilical cord donors) has been obtained prior to any intervention.".
