Illustrates the MSCs viability and proliferation after 24 and 48 hours of culture on SiONx-Ti and SiONPx-Ti compared to the anodized-Ti. A) Fluorescence images show the live cells (green) and dead cells (red) on the tested surfaces which indicated a good cells adhesion and spread on the surfaces. B) MTS cell’s viability/proliferation assay presented in optical density (OD) indicates higher cells proliferation on the PECVD coatings compared to the anodized-Ti, but no significant difference was observed.
