“…These peritruncal vessels were remodeled and interconnected with the aortic endothelium (Chen et al, 2014a(Chen et al, , 2014bIvins et al, 2015;Thé veniau-Ruissy et al, 2016). The first step requires several molecules including VEGF-C (Chen et al, 2014a(Chen et al, , 2014b, C-X-C motif chemokine ligand 12 (Ivins et al, 2015), and the collagen-and calcium-binding EGF-like domains 1 protein (Bonet et al, 2018). Deletion of these signals results in a lack of ASVs and hypoplastic peritruncal CVs, leading to a decrease in the number of CA stems (Chen et al, 2014a(Chen et al, , 2014bIvins et al, 2015;Thé veniau-Ruissy et al, 2016).…”
