Despite its importance, the resorptive surface of osteoclasts has not been directly visualised. We exploited a novel approach that enables us to inspect the substrate-apposed surface of cells. To achieve this, we incubated osteoclasts on vitronectin-coated nail varnish and, afterwards, we dissolved the substrate and visualised the cells resorbing-side up in the scanning electron microscope (SEM). We then employed confocal microscopy to correlate the SEM appearances with the di...
