Low back pain is a common disorder in the clinical treatment of the Department of Orthopedics. Lumbar intervertebral disc degeneration is a main reason for the chronic pain and the process is difficult to reverse. Traditional treatment methods include conservative treatment and surgical treatment. Although the clinical symptoms caused by intervertebral disc degeneration can be alleviated to a certain extent, these treatment methods do not solve the fundamental issues and they also produce corresponding complications. The rise of tissue engineering technology and its applications in different fields have brought new ideas for the treatment of intervertebral disc degeneration. This book discusses the fundamentals as well as more recent developments in stem cell therapy and tissue engineering technology and offers an alternative for treating degeneration of intervertebral discs.

Disorders related to the intervertebral disc (IVD) are common causes of morbidity and of severe life quality deterioration. IVD degeneration, although in many cases asymptomatic, is often the origin of painful neck and back diseases. In Western societies IVD related pain and disability account for enormous health care costs as a result of work absenteeism and thus lost production, disability benefits, medical and insurance expenses. Although only a small percentage of patients with disc disorders finally will undergo surgery, spinal surgery has been one of the fastest growing disciplines in the musculoskeletal field in recent years. Nevertheless, current treatment options are still a matter of controversial discussion. In particular, they hardly can restore normal spine biomechanics and prevent degeneration of adjacent tissues. While degeneration affects all areas of the IVD, the most constant and noticeable changes occur in the gel-like central part, the nucleus pulposus (NP). Recent emphasis has therefore been put in biological ways to regenerate the NP; however, there are a number of obstacles to overcome, considering the exceptional biological and biomechanical environment of this tissue. Different biological approaches such as molecular, gene, and cell based therapies have been investigated and have shown promising results in both in vitro and in vivo studies. Nonetheless, considerable hurdles still exist in their application for IVD regeneration in human patients. The choice of the cells and the choice of the cell carrier suitable for implantation pose major challenges for research and development activities. This lecture recapitulates the basics of IVD structure, function, and degeneration mechanisms. The first part reviews the recent progress in the field of disc and stem cell based regenerative approaches. In the second part, most appropriate biomaterials that have been evaluated as cell or molecule carrier to cope with degenerative disc disease are outlined. The potential and limitations of cell- and biomaterial-based treatment strategies and perspectives for future clinical applications are discussed.

Degenerative disc disease (DDD) is implicated as one of the primary causes of lower back pain (LBP), the leading cause of disability worldwide. This degeneration is characterized by irreversible detrimental changes to the structure of the intervertebral disc (IVD) which then severely impairs its mechanical function in the spine. The gel-like nucleus pulposus (NP) at its core loses its ability to hydrate while damage propagates through the surrounding annulus fibrosus (AF) in the form of tears and lesions, rendering it unable to resist elastic deformation. Current surgical interventions treat the painful symptoms of the disease rather than the underlying causes, providing only a temporary solution. Tissue-engineered (TE) repair strategies have been proposed for the last two decades as a means of preventing disease advancement in the long term, aiming to restore the native disc's structure as well as repair damage to the cell population. While promising, recapitulating the disc's complex fibrous architecture and mechanical behavior represents an enduring challenge in the field, particularly in attempts to scale up to larger animal models for clinical translation.This thesis sought to augment engineered constructs in vitro by investigating the interplay between matrix composition and mechanical behavior, as well as provide mechanical support to constructs for in vivo delivery. In particular, it describes how the manipulation of fiber formation through media glucose content in vitro plays a critical role in governing matrix structure and mechanical integrity (Chapter 1); how these same mechanisms function in a diseased state in vivo to influence the developing disc (Chapter 2); and how providing a supplemental cage structure to immature TE-IVDs can prevent initial displacement and collapse following implantation to eventually ensure successful tissue integration. Collectively, the work presented here offers crucial insight into how to continue the advancement of biologically based TDR strategies towards use in the clinic.

Download The Intervertebral Disc Book in PDF, ePub and Kindle
The intervertebral disc is a complex structure that separates opposing vertebrae, permits a wide range of motion, and accommodates high biomechanical forces. Disc degeneration leads to a loss of function and is often associated with excruciating pain. Written by leading scientists and clinicians, the first part of the book provides a review of the basic biology of the disc in health and disease. The second part considers strategies to mitigate the effects of disc degeneration and discusses the possibility of engineering replacement tissues. The final section is devoted to approaches to model normal development and elucidate the pathogenesis of degenerative disc disease using animal, organ and cell culture techniques. The book bridges the gap between the basic and clinical sciences; the target audience includes basic scientists, orthopaedists and neurologists, while at the same time appealing to the needs of graduate students, medical students, interns and fellows.

Abstract: Intervertebral disc tissue engineering is challenging because it involves the integration of multiple tissues with distinct structures and compositions such as lamellar annulus fibrosus, gel'like nucleus pulposus and cartilage endplate. Each of them has different compositions and different structures. It is hypothesized that integration of tissues can be enhanced with appropriate mechanical and biological stimuli. Meanwhile, effect of torsional stimulus on cell re'orientation in mesenchymal stem cell'collagen tubular constructs is investigated in this study. Furthermore, it is proposed that these findings can be used to fabricate a multicomponent unit for intervertebral disc tissue engineering. It has been demonstrated that mechanical and biological stimuli can stabilize the interface between osteogenic and chondrogenic differentiated constructs with enhanced ultimate tensile stress while the phenotype of osteogenic and chondrogenic differentiated constructs were maintained. Scanning electronic microscopic images have shown aligned collagen fibrils and presence of calcium at the interface, indicating the possibility of the formation of a calcified zone. In addition, it is proven that torsional stimulus triggered re'orientation of mesenchymal stem cells in collagen lamellae towards a preferred angle. Cell alignments were confirmed by using a MatLab'based program to analyze the actin filament and the cell alignment via Phalloidin and Hematoxylin staining, respectively. Cells and actin filaments were inclined around 30o from the vertical axis, while cells and filaments in the control group (static loading) aligned along the vertical axis. Furthermore, a double'layers bioengineered unit was fabricated, with intact osteogenic differentiated parts at both ends. Comparatively higher cell density was observed at the interface between layers, demonstrating the interactions between layers, while the phenotype of each part was maintained in 14 days culture. This study concludes that a multi'components bioengineered unit with preferred cell alignments can be fabricated. This provides new insights to future development of bioengineered spinal motion segment for treating late stage disc degeneration.

Download Tissue Engineering of the Intervertebral Disc Using Chemical and Mechanical Stimulation of Mesenchymal Stem Cells Book in PDF, ePub and Kindle
The intervertebral disc (IVD) is a composite structure that allows bending, twisting of and load transfer through the spine. Disc damage often begins with tears in the outer annulus fibrosus (AF), allowing the inner nucleus pulposus (NP) to herniate through the weakened AF. If this condition is allowed to continue, full disc degeneration will result. Current treatment options are limited, and invasive surgical intervention can cause further degradation of the adjacent discs. This dissertation discusses how the pillars of tissue engineering are used to develop constructs for whole intervertebral disc replacement. Specifically, it describes the effects of chemical (chapters 4 and 5) and mechanical (chapter 2) stimulation, cell source (chapter 3), and scaffold materials (appendix A) on the development of tissue engineered IVDs both in vitro and in vivo.
