Phospholipid-coatings on metallic implant surfaces were evaluated in terms of adhesion, proliferation and matrix production of skeletal cells, and of macrophage stimulation. The working hypothesis is that mimicking a model biomembrane by phospholipids on surfaces to which cells adhere, the surface recognition by surrounding cells is altered. In this study, 1) mirror-like polished Ti-6Al-7Nb and...

We investigated interactions of the lipid raft molecules sphingomyelin (SM) and cholesterol (CHOL) in monolayers and bilayers composed of 1-palmitoyl-2-oleoyl-sn-glycerophosphatidylethanolamine (POPE) or 1-palmitoyl-2-docosahexaenoyl-sn-glycerophosphatidylethanolamine (PDPE) at 35 degrees C. Techniques employed were pressure-area (pi-A) isotherms generated from Langmuir-Blodgett films, solid-st...
