There is an error in the Funding statement detailed in the Acknowledgments section. The correct phrasing and number for “Instituto Carlos III (PI17/00336)” is “project PI17/00335, integrated in the National R+ D+ I and funded by the ISCIII and the European Regional Development Fund.”
A correction has been made to the Acknowledgments section:
“This work was supported in part by Fundació La Marató de TV3 (201516-10, 201502-30), SGR programme of Generalitat de Catalunya (2017-SGR-301 REMAR Group), ISCIII-REDinREN (RD16/0009 Feder Funds) and Instituto Carlos III project PI17/00335, integrated in the National R+ D+ I and funded by the ISCIII and the European Regional Development Fund. LC-P by the Spanish Government FPU grant (Formación de Personal Universitario, FPU17/01444); MM-T is sponsored by the PERIS (SLT002/16/00234) from the Generalitat de Catalunya; FB is a researcher from Fundació Institut de Recerca en Ciències de la Salut Germans Trias i Pujol, supported by the Health Department of the Catalan Government (Direcció General de Recerca i Innovació, Department Salut, Generalitat de Catalunya) and MF is funded by the Catalan Health Department (Generalitat de Catalunya) contract PERIS (SLT002/16/00069); the authors also want to thank Miriam Morón-Font for the graphical art help.”
Additionally, in the original article, there was a mistake in Figure 3 as published. In the X axis of the figure, instead of B+ MSC-FP, it should be B+ MSC-PF. The corrected Figure 3 appears below. The authors apologize for these errors and state that they do not change the scientific conclusions of the article in any way. The original article has been updated.
Figure 3.
Concentration of IL-10 and TNFα in the culture medium after 7 days of B cell culturing with the different conditions measured by ELISA. Each dot represents a different combination of MSC and B cells donors. Statistical significance (p < 0.05) was determined by Kruskall-Wallis with Dunn's multi-comparison test (*p ≤ 0.05, **p ≤ 0.01, ****p ≤ 0.0001). MSC, mesenchymal stem cells; CM, conditioned medium; EV, extracellular vesicles; PF, protein fraction.
