Correction to: Nature Medicine https://doi.org/10.1038/s41591-020-0844-1, published online 11 May 2020.

In the version of this article initially published, two concentrations were incorrect (“3 ml of 100 μg ml⁻¹ collagenase IV” and “final concentration of 1,250 μg ml⁻¹”) at the end of the final sentence of the Methods subsection ‘NSCLC PDEC protocol’. The correct statement is as follows: “...3 ml of 100 mg ml⁻¹ collagenase IV (Thermo Fisher Scientific, cat. no. NC9836075) to a final concentration of 100 μg ml⁻¹.” The error has been corrected in the HTML and PDF versions of the article.
