From: Response of Osteoclasts to Titanium Surfaces with Increasing Surface Roughness: An In Vitro Study
Morphology of osteoclast adhesions structures. Confocal micrographs of differentiated osteoclasts immunostained for F-actin (green) and cell nuclei (blue) on TS (a) and bone (b). Osteoclasts showed formation of podosomes (mainly on TS) and actin ring formation (here exemplary shown on bone), both indicated with white arrows. White circles indicate filopodia extending from the cell periphery
