Intraosseous transcutaneous amputation prostheses (ITAPs) allow direct loading of the skeleton, but their success is limited by infection resulting from breaching of the skin at the interface with the implant. Keratinocytes provide the skin\u2019s primary barrier function, while hemidesmosomes mediate their attachment to natural ITAP analogues. Keratinocytes must attach directly to the surface of the implant. We have assessed the proliferation, morphology and attachment of keratinocytes to four titaniumalloy surfaces in order to determine the optimal topography in vitro. We used immunolocalisation of adhesion complex components, scanning electron microscopy and transmission electron microscopy to assess cell parameters.<\/jats:p>\n                  <jats:p>We have shown that the proliferation, morphology and attachment of keratinocytes are affected by the surface topography of the biomaterials used to support their growth. Smoother surfaces improved adhesion. We postulate that a smooth topography at the point of epithelium-ITAP contact could increase attachment in vivo, producing an effective barrier of infection.<\/jats:p>","DOI":"10.1302\/0301-620x.90b1.19580","type":"journal-article","created":{"date-parts":[[2007,12,26]],"date-time":"2007-12-26T11:07:43Z","timestamp":1198667263000},"page":"114-121","source":"Crossref","is-referenced-by-count":66,"title":["Sealing the skin barrier around transcutaneous implants"],"prefix":"10.1302","volume":"90-B","author":[{"given":"C.
