Surface modification of polystyrene Petri dishes by plasma polymerized 4,7,10-trioxa-1,13-tridecanediamine for enhanced culturing and migration of bovine aortic endothelial cells.

This study investigates the efficiency of a plasma polymerized 4,7,10-trioxa-1,13-tridecanediamine (ppTTDDA) film coated on a polystyrene (PS) Petri dish, which is a biocompatible surface with carbon- and oxygen-based chemical species. The adhesion, proliferation, and migration properties of bovine aortic endothelial cells (BAECs) were profoundly enhanced in the ppTTDDA-coated PS Petri dishes without extracellular matrix (ECM) proteins, when compared with the uncoated PS Petri dishes. These observations indicate that ppTTDDA-coated PS Petri dishes can directly interact with cells, regardless of cell adhesion molecules. The increased cell affinity was attributed to the high concentration of carboxyl group on the surface of the ppTTDDA film. Such a carboxyl surface showed an excellent ability to promote culturing of BAECs. Plasma surface modification techniques are effective in improving biocompatibility and provide a surface environment for cell culture. PMID: 32942906 [PubMed - as supplied by publisher]
