In the Materials and Methods section, the Ethical Considerations paragraph incorrectly noted the regulatory permit approval numbers for this study. The first sentence of the paragraph should have stated the following:
The production of clinical-grade MSCs was accredited by the Swedish National Board of Health and Welfare (approval numbers 6.3.3-8874-2011 and 6.1.3-9791/2013).
The authors regret the error, which has been corrected in the online version of the article.
