Four different surface topographies were obtained on titanium-6aluminum-4vanadium plates by varying laser processing parameters and strategies: surfaces presenting nanostructures such as laser-induced periodic surface structures (LIPSS) and \u2018spikes\u2019, associated or not with more complex multiscale geometries combining micro-pits, nanostructures and stretches of polished areas. After sterilization by heat treatment, LIPSS and spikes were characterized to be highly hydrophobic, whereas the original polished surfaces remained hydrophilic. Human mesenchymal stem cells (hMSCs) grown on simple nanostructured surfaces were found to spread less with an increased motility (velocity, acceleration, tortuosity), while on the complex surfaces, hMSCs decreased their migration when approaching the micro-pits and preferentially positioned their nucleus inside them. Moreover, focal adhesions of hMSCs were notably located on polished zones rather than on neighboring nanostructured areas where the protein adsorption was lower. All these observations indicated that hMSCs were spatially controlled and mechanically strained by the laser-induced topographies. The nanoscale structures influence surface wettability and protein adsorption and thus influence focal adhesions formation and finally induce shape-based mechanical constraints on cells, known to promote osteogenic differentiation.<\/jats:p>","DOI":"10.3390\/nano10050864","type":"journal-article","created":{"date-parts":[[2020,5,4]],"date-time":"2020-05-04T03:29:39Z","timestamp":1588562979000},"page":"864","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":59,"title":["Ultrafast Laser Processing of Nanostructured Patterns for the Control of Cell Adhesion and Migration on Titanium Alloy"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9618-2715","authenticated-orcid":false,"given":"Antoine","family":"Klos","sequence":"first","affiliation":[{"name":"SAINBIOSE Laboratory INSERM U1059, University of Lyon, Jean Monnet University, F-42270 Saint Priest en Jarez, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4072-492X","authenticated-orcid":false,"given":"Xxx","family":"Sedao","sequence":"additional","affiliation":[{"name":"Hubert Curien Laboratory, University of Lyon, Jean Monnet University, UMR 5516 CNRS, F-42000 Saint-Etienne, France"},{"name":"GIE Manutech-USD, 20 rue Benoit Lauras, F-42000 Saint-Etienne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7117-8699","authenticated-orcid":false,"given":"Tatiana E.","family":"Itina","sequence":"additional","affiliation":[{"name":"Hubert Curien Laboratory, University of Lyon, Jean Monnet University, UMR 5516 CNRS, F-42000 Saint-Etienne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3197-601X","authenticated-orcid":false,"given":"Cl\u00e9mentine","family":"Helfenstein-Didier","sequence":"additional","affiliation":[{"name":"Laboratory of Tribology and Systems Dynamics, National School of Engineers of Saint-Etienne, University of Lyon, UMR 5513 CNRS, F-42100 Saint-Etienne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5484-7114","authenticated-orcid":false,"given":"Christophe","family":"Donnet","sequence":"additional","affiliation":[{"name":"Hubert Curien Laboratory, University of Lyon, Jean Monnet University, UMR 5516 CNRS, F-42000 Saint-Etienne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sylvie","family":"Peyroche","sequence":"additional","affiliation":[{"name":"SAINBIOSE Laboratory INSERM U1059, University of Lyon, Jean Monnet University, F-42270 Saint Priest en Jarez, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2110-287X","authenticated-orcid":false,"given":"Laurence","family":"Vico","sequence":"additional","affiliation":[{"name":"SAINBIOSE Laboratory INSERM U1059, University of Lyon, Jean Monnet University, F-42270 Saint Priest en Jarez, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0745-5417","authenticated-orcid":false,"given":"Alain","family":"Guignandon","sequence":"additional","affiliation":[{"name":"SAINBIOSE Laboratory INSERM U1059, University of Lyon, Jean Monnet University, F-42270 Saint Priest en Jarez, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2380-7531","authenticated-orcid":false,"given":"Virginie","family":"Dumas","sequence":"additional","affiliation":[{"name":"Laboratory of Tribology and Systems Dynamics, National School of Engineers of Saint-Etienne, University of Lyon, UMR 5513 CNRS, F-42100 Saint-Etienne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,30]]},"reference":[{"key":"ref_1","unstructured":"Hanawa, T.
