As induction of angiogenesis in aneurysm has been reported12 and partial EndMT13 has been described in angiogenesis and would be likely in the vessel wall, we investigated the mRNA expression for VEGF family ligands, receptors, and co-receptors (Supplementary Table 9, age-corrected data from Folkersen et al. 7). Here, VEGFA is linked to aneurysm.
