Correction to: npj Regenerative Medicine 10.1038/s41536-018-0045-4, published online 16 February 2018
The original version of the published Article contained an error in the initial cross depicted in Fig. 2. The initial cross should be a male mTRHet heterozygous animal crossed with a female mdx4cv/4cv homozygous animal.
This has been corrected in the HTML and PDF version of the Article.
