Figure 3From: Cytotoxic effects of cobalt and nickel ions on osteocytes in vitroPhase microscopic observation of MLO-Y4 osteocytes after metal ion treatment for 24 hr. Round-shaped cells that lost long dendritic cell processes characteristic to MLO-Y4 osteocytes were observed in both Co- and Ni-ion-treated cells at 0.50 mM (arrowheads). Scale bar =50 μm.Back to article page
