After each treatment, globular and lamellar microstructures were obtained. Saos-2 pre-osteoblast human osteosarcoma cells were seeded onto Ti6Al4V alloy disks and immersed in cell culture for 7 days. Electrochemical assays in situ were performed using OCP and EIS measurements. Impedance data show a passive behavior for the three Ti6Al4V alloys; additionally, enhanced impedance values were recorded for Ti6Al4V800 and Ti6Al4V1050 alloys. This passive behavior in culture medium is mostly due to the formation of TiO2 during their sterilization. Biocompatibility and cell adhesion were characterized using the SEM technique; Ti6Al4V as received and Ti6Al4V800 alloys exhibited polygonal and elongated morphology, whereas Ti6Al4V1050 alloy displayed a spherical morphology. Ti and O elements were identified by EDX analysis due to the TiO2 and signals of C, N and O, related to the formation of organic compounds from extracellular matrix. These results suggest that cell adhesion is more likely to occur on TiO2 formed in discrete \u03b1-phase regions (hcp) depending on its microstructure (grains).<\/jats:p>","DOI":"10.3390\/ma10040445","type":"journal-article","created":{"date-parts":[[2017,4,24]],"date-time":"2017-04-24T13:10:11Z","timestamp":1493039411000},"page":"445","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Osteoblast Cell Response on the Ti6Al4V Alloy Heat-Treated"],"prefix":"10.3390","volume":"10","author":[{"given":"Mercedes","family":"Ch\u00e1vez-D\u00edaz","sequence":"first","affiliation":[{"name":"Departamento de Ingenier\u00eda en Metalurgia y Materiales, Instituto Polit\u00e9cnico Nacional (ESIQIE-IPN), UPALM Zacatenco, Ciudad de M\u00e9xico 07738, Mexico"},{"name":"Departamento de Ingenier\u00eda de Superficies, Corrosi\u00f3n y Durabilidad, Centro Nacional de Investigaciones Metal\u00fargicas (CENIM-CSIC), Madrid 28040, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda","family":"Escudero-Rinc\u00f3n","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda de Superficies, Corrosi\u00f3n y Durabilidad, Centro Nacional de Investigaciones Metal\u00fargicas (CENIM-CSIC), Madrid 28040, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elsa","family":"Arce-Estrada","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda en Metalurgia y Materiales, Instituto Polit\u00e9cnico Nacional (ESIQIE-IPN), UPALM Zacatenco, Ciudad de M\u00e9xico 07738, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rom\u00e1n","family":"Cabrera-Sierra","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda Qu\u00edmica Industrial, Instituto Polit\u00e9cnico Nacional (ESIQIE-IPN), UPALM Zacatenco, Ciudad de M\u00e9xico 07738, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,4,23]]},"reference":[{"key":"ref_1","unstructured":"Ratner, B.D., Hoffman, A.S., Schoen, F.J., and Lemons, J.E.
