In this Article, the blots in Extended Data Figs 9 and 11 were inadvertently taken from different replicates of the same experiment. In the Supplementary Information to this Amendment, we have replaced these blots with the corresponding replicate experiment, shown together with the original figures for comparison. In addition, Supplementary Fig. 1 of the original Article has been revised to include the corresponding uncropped western blot images, including the correct matching blots shown in the original Figs 2a (ERK1/2), 3b (PI3K/P85 and VE-cadherin), 3d, 4h (pAKT, pERK1/2 and pVEGFR2), 4i (pERK1/2), and Extended Data Figs 1b (PlxnD1), 1c (GAPDH), 1d (NRP1 and GAPDH), 1f (Gαq/11 and GAPDH), 1g (GAPDH), 3a (peNOS, pAkt and pERK1/2), 7d (VEGFR2), and 8. Replicates for all blots are provided. These changes do not affect the results or conclusions of the Article, and we apologise for any inconvenience these errors may have caused. The original Article has not been corrected online
