Bioadhesive Hydrogel Composite Cell Carrier For The Repair Of The Degenerated Intervertebral Disc, Thomas Richard Christiani

Theses and Dissertations

Lower back pain (LBP) affects the worldwide population and can be attributed to the degeneration of the intervertebral disc (IVD). The IVD is composed of a central nucleus pulposus (NP), a peripheral annulus fibrosus (AF), and adjacent cartilage endplates (CEPs). IVD degeneration is characterized by proteoglycan loss, tissue dehydration, and decreased hydrostatic pressure. In this work, the use of an injectable bioadhesive hydrogel composite for replacement of the degenerated NP was investigated.

Results indicate that the composite exhibits similar mechanical properties to the NP, adheres to AF tissue, and supports encapsulated mesenchymal stem cell (MSC) differentiation toward an NP-like phenotype …
