Paper Title:
Lamellar Surface Structures on Stainless Steel 316 LVM and their Influence on Osteoblastic Cells
  Abstract

In this study, nanoscaled lamellar surface structures were prepared on medical stainless steel by chemical etching of the decomposed phases and their effect on the morphology of osteoblastic cells was investigated using Field Emission Scanning Electron Microscopy. Long filopodia were grown from the cells perpendicular to the lamellar structure while almost no or only short filopodia are formed parallel to the lamellae. The results are explained by a different surface roughness parallel and perpendicular to the lamellae: During the growth process of the filopodia a nearly flat surface is recognized parallel to the lamellae while a topographical change is sensed perpendicular to the structure, which is preferred by the cells.
