Figure 2From: Differentiation of monocytes into multinucleated giant bone-resorbing cells: two-step differentiation induced by nurse-like cells and cytokinesScanning electron micrographs of dentin slices, showing (a) resorption areas formed on dentin by TRAP-positive multinucleated giant cells derived from monocytes and stimulated with granulocyte-macrophage-colony-stimulating factor for 96 h and (b) a control slice incubated with the TRAP-positive mononuclear cells in the absence of cytokines. Scale lines = 50 μm.Back to article page
