RBMCs were seeded at an initial density of 4 × 104 cells/cm2 onto the titanium surfaces of the three groups and allowed to attach to the surface for 1, 3, 6, and 24 h. A total of 50 μL CellTiter-Blue® Reagent (Promega Corporation, Madison, WI, USA) diluted in 250 μL phosphate-buffered saline (PBS) was used to count the number of RBMC adhesions. The analysis was carried out in accordance with the manufacturer’s instructions. The cells were labeled and observed after 24 h of culture, as described in our prior research [30 (link),31 (link),32 (link),33 (link),34 (link)].
