The authors wish to make the following correction to their paper [1]: In Figure 1B, we quoted PCDRGs were supplemented with NGF+ but it should have been MScCM. In order to correct this mistake, we have substituted the correct MScCM supplementation in Figure 1B below. This change has no material impact on the rest of the figure, or the legend, results, discussion and conclusions of our paper.

The authors would like to apologize for any inconvenience caused to the readers by these changes. The manuscript will be updated and the original will remain online on the article webpage, with a reference to this Correction.
