  1. IVD specific marker genes. Genes identified by NP vs AC microarray comparison. Mean fluorescence intensity is shown for each cell type (AC, AF and NP) along with calculated fold change values (positive and negative) between NP and AC cells that were greater than 100. Highlighted in bold are genes that were taken forward for qRT-PCR and italicised are genes that were identified in previous array studies [23,24]. AC, articular cartilage; AF, annulus fibrosus; NP, nucleus pulposus; qRT-PCR, quantitative real time polymerase chain reaction.
