Surface wettability of plasma SiO x :H nanocoating-induced endothelial cells' migration and the associated FAK-Rho GTPases signalling pathways

Abstract: Vascular endothelial cell (EC) adhesion and migration are essential processes in re-endothelialization of implanted biomaterials. There is no clear relationship and mechanism between EC adhesion and migration behaviour on surfaces with varying wettabilities. As model substrates, plasma SiO x :H nanocoatings with well-controlled surface wettability (with water contact angles in the range of 98.5 + 2.38 to 26.3 + 4.08) were used in this study to investigate the effects of surface wettability on cell adhesion/mig… Show more

“…In previous works, we demonstrated the important contribution to cell migration and adhesion by cytoskeletal reorganization associated with focal adhesions assembly when the cells overexpressed Id1 [14], stimulated by various concentrations of oxLDLs (oxidized low-density lipoprotein) at static conditions [15 -17], placed on surfaces with different degrees of wettability [18,19] or LDL treatment under shear stress [20,21]. It is well established that cells use actin polymerization coupled with integrin-mediated adhesion to generate lamellipodial protrusions at the cell front to migrate on two-dimensional substrates [2].…”

“…Ранее упоминалось о неоднородности ЕРСs, функциональных и фено-типических различиях прогениторных и зрелых эндотелиальных клеток. Немногочисленные ис-следовательские работы проведены на разных типах клеток (ЕРС, HUVEC, EA.hy 926) [54][55][56], поэтому результаты не поддаются сравнению. Однако, при всех равных условиях, физические свойства поверхности металла, такие как гидро-фильность и шероховатость, оказывают боль-шое влияние на адгезию и функциональные ха-рактеристики культивируемых на поверхности металла эндотелиальных клеток [54].…”

“…Работа Shen Y. и соавторов посвящена влия-нию гидрофобных/гидрофильных свойств по-верхности на адгезию и миграцию ECs [56]. С помощью плазменного нанопокрытия SiOx:Н, позволяющего хорошо контролировать уровень смачиваемости, выполнена обработка метал-лической поверхности образцов (краевой угол смачивания составил диапазон от 98.5+2.38о до 26.3+4.08о).…”
