In extreme case contemporary treatment of degenerative diseases such arthrosis or traumatic bone damage is replacement of the joint or bone implant. Implant material, mostly metal, ceramics or polymer, is a foreign material for the organism that causes the reaction of surrounding tissue. It can be inflammation, infection, insufficient healing, aseptic loosening, etc. Only between 2002 and 2012, 12,662 patients had to undergo an artificial joint replacement surgery in the Czech Republic, which cost CZK 1.1bn. Any complications in interacting the surface of the implant with the surrounding tissues can be eliminated by surface modification of the material, eventually by adapting the material to the patient's organism. One possibility is to cultivate the patient's autologous cells on the surface of the implant. Due to the fact that cells on the smooth surface of the material can badly adhere, the surface must be first modified, for example by grooving, diamond coating, etc. Appropriate surface modification can increase cell osseointegration and reduce the complications of healing of implant in the bone. The aim of the thesis is differentiation of stem cells to osteoblasts on the Ti6Al4V titanium alloy surface. Several forms of titanium surface treatment (mechanical - polishing, sanding, grooving, plasma spraying, anodizing, DLC coating) will be tested and the most suitable surface to increase the adhesion of stem cells to titanium will be selected. Mesenchymal stem cells will be differentiated into osteoblasts, it will be enhanced by dynamic stimulation that provides conditions similar to the in vivo organism.
