Correction to: Nature Communications https://doi.org/10.1038/s41467-019-12472-3, published online 3 October 2019.

In the original version of this Article the ethical registration number permitting collection of amniotic membranes in the Human samples subsection of the “Methods” section was mis-cited as 2017-00101. The correct number refers to the pre-Basec study PB_2017-00101, which is not listed in the Register of Research Projects in Switzerland (RAPS). The old reference number of this study is 14-273 and can be found in a list of protocols submitted before 2015 (https://www.ge.ch/document/liste-protocoles-soumis-2015).

This has been corrected in both the PDF and HTML versions of the Article.
