Development Of Novel Inks And Approaches For Printing Tissues And Organs, Shen Ji
Dissertations
Tissue engineering is a multidisciplinary field that investigates and develops new methods to repair, regenerate and replace damaged tissues and organs, or to develop biomaterial platforms as in vitro models. Tissue engineering approaches require the fabrication of scaffolds using biomaterials or fabrication of living tissues using cells. As the demands of customized, implantable tissue/organs are increasing and becoming more urgent, conventional scaffold fabrication approaches are difficult to meet the requirements, especially for complex large-scale tissue fabrication. In this regard, three-dimensional (3D) printing attracted more interest over the past decades due to its unrivaled ability to fabricate highly customized tissues or …
Bioadhesive Hydrogel Composite Cell Carrier For The Repair Of The Degenerated Intervertebral Disc, Thomas Richard Christiani
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 …
