Based on their previous involvement in graft rejection or angiogenesis and the FC in their differential expression between ECD and non-ECD patients, five genes were selected (CXCL1, VWA7, CCL4, IL1-β, IFN-γ) for further quantitative RT-PCR (qPCR) validation in the PRAT-SVF samples used to perform transcriptomic analysis (Supplementary Table 10). This evidence concerns the gene CXCL1 and familial atrioventricular septal defect.
