Immunohistochemical staining for receptor activator of nuclear factor kappa B (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) in normal rat intervertebral disc (IVD) tissues (anulus fibrosus (AF) (a-d); nucleus pulposus (NP) (e-h); cartilaginous endplate (CEP) (i-l)). Paraffin-embedded sections of rat IVDs (12-week-old male rats (n = 2)) were stained with mouse monoclonal anti-RANK antibody (a, e, i), rabbit polyclonal anti-RANKL antibody (b, f, j), or goat polyclonal anti-OPG antibody (c, g, k). Isotype controls are shown in d, h and l. Scale bar 10 μm
