Correction to: Nature Communications https://doi.org/10.1038/s41467-019-09605-z, published online 05 April 2019.

The original version of this Article contained errors in Figs. 1, 3 and 4. In panels b and d of Fig. 1, the labels ‘Sdc4-/-’ were inadvertently replaced by ‘Sdc4+/+’. In panels c and d of Fig. 3, the labels ‘Sdc4-/-’ were replaced by ‘Sdc2-/-’. In panel f of Fig. 3, the labels ‘FGF2’ were replaced by ‘VEGFA165’. In panel e of Fig. 6, a ‘Sdc2-/-‘ label was inadvertently included. This has now been corrected in the PDF and HTML versions of the Article.
