Abstract | Tissue engineering has been conducted in the study of cardiovascular grafts for many years. Many obstacles have been overcome in this rapidly changing field, but one difficulty has remained until now: the large number of endothelial cells (ECs) needed for seeding the inner layer of bypass graft. Recent advances in endothelial progenitor cell (EPC) isolation and culture techniques have increased the interest in genetic studies. Despite these advances in EPC studies, the "gold standard" for the seeding of tissue engineering constructs or hybrid grafts remains mature human umbilical vein endothelial cells (HUVECs). This study investigates the ability of HUVECs to be expanded in culture to provide sufficient cells for graft seeding. The levels of gene expression of key genes are then examined to ensure that these cells retain the EC phenotype. This study demonstrates that HUVECs may be cultured for up to 12 passages without alteration in phenotype. Subsequent passage numbers are sufficiently similar to those preceding them to allow cells of different passages to be mixed without gene expression anomalies. |
