MTT cell metabolic activity assay. hUC-MSC and CHO-k1 cell adhesion and proliferation results on the two different types of titanium discs (laser-processed titanium (LPT) and Ti control) at different times (3 h, and 1, 3, and 7 days). ***Statistically significant differences between cell types at p < 0.001; ### represents statistically significant differences between Ti surfaces p < 0.001. Data represent means of three independent experiments and SD. MTT, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, OD optical density
