Detection of mRNA expression of receptor activator of nuclear factor kappa B (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) in rat anulus fibrosus (AF), nucleus pulposus (NP) and cartilaginous endplate (CEP) cells. Significantly higher mRNA expression levels of RANKL were found in CEP cells than those in AF and NP cells; *p < 0.05. There were no significant differences in expression levels of RANK and OPG among AF, NP and CEP cells
