Book excerpt: Degeneration of the intervertebral disc (IVD) is a significant cause of pain and immobility for many people. Tissue engineering with mesenchymal stem cells (MSC) offers promise for repair or regeneration of disc tissue if they can be encouraged to differentiate to a nucleus pulposus phenotype. The cells were exposed to conditions approximating the in vivo extracellular environment of the IVD; low glucose (2.5 mg/mL), 5% hypoxia, and medium conditioned by the cells of the nucleus pulposus (notochordal and chondrocyte-like). A novel hydrostatic pressure bioreactor was designed and validated to simulate physiologic-range pressures (1MPa at 0.5 Hz and static) to in vitro cultures of MSC. These conditions were compared to the "standard" cell culture conditions of 4.5 mg/mL glucose, 20% oxygen, no hydrostatic pressure, and a "neutral" conditioned medium. The bioreactor was shown to not adversely affect cell culture and MSC were sensitive to all factors tested.
