Correction to: Nature Biomedical Engineering https://doi.org/10.1038/s41551-018-0284-0, published online 17 September 2018.

In the version of this article originally published, in Fig. 8, duplicated histological images for the heart in the PBS control group at day 28 (panel a) and at day 43 (panel b) were inadvertedly used. Due to the age of the paper, the figure cannot be replaced online. Figure 1 below (revised Fig. 8) serves to correct the article. This correction does not affect the results and conclusions reported in the paper.
