                         treatment to enable good bone growth and implant integration. In 
                         this work, three treatments that modify the titanium alloy surface 
                         were studied with the aim of promoting osteogenic differentiation 
                         of human-embryonic-stem-cell-derived mesenchymal progenitors 
                         (hESC-MPs). The surface treatments used were mechanical polishing 
                         and electropolishing for 4 or 12 min in an H2SO4/HF/glycerine 
                         solution. The samples were characterised by atomic force 
                         microscopy, profilometry, X-ray photoelectron spectroscopy, and 
                         wettability. Samples were seeded with hESC-MPs in osteogenic 
                         media, and the cell number and alkaline phosphatase activity were 
                         measured. The electropolishing surface treatments influenced the 
                         nanometric morphology and wettability. However, the 
                         electropolished surfaces contributed in the same way as the 
                         mechanically polished surface to osteogenic differentiation, 
                         indicating that differentiation was strongly influenced by 
                         microroughness, which did not differ among the treatments used in 
                         the present work.",
