Article Abstract
Intervertebral disc (IVD) degeneration is one of the major causes of lower back pain, a common health condition that greatly affects the quality of life. With an increasing elderly population and changes in lifestyle, there exists a high demand for novel treatment strategies for damaged IVDs. Researchers have investigated IVD tissue engineering (TE) as a way to restore biological and mechanical functions by regenerating or replacing damaged discs using scaffolds with suitable cells. These scaffolds can be constructed using material extrusion additive manufacturing (AM), a technique used to build three-dimensional (3D), custom discs utilising computer-aided design (CAD). Structural geometry can be controlled via the manipulation of printing parameters, material selection, temperature, and various other processing parameters. To date, there are no clinically relevant TE-IVDs available. In this review, advances in AM-based approaches for IVD TE are briefly discussed in order to achieve a better understanding of the requirements needed to obtain more effective, and ultimately clinically relevant, IVD TE constructs.

Intervertebral disc degeneration (IDD) is a major cause of low back pain (LBP), significantly affecting on global disability and healthcare costs. Traditional treatments primarily focus on symptom management rather than addressing the underlying causes, such as the decline in nucleus pulposus (NP) cells and reduced extracellular matrix (ECM) synthesis. Cell therapy shows promise by replenishing NP cells, activating resident cells, and enhancing ECM deposition.

Despite extensive investigations into the genetic predisposition to IDD, the precise pathogenic genes and molecular pathways involved remain inadequately characterized, underscoring the need for continued research to clarify its genetic underpinnings.
Methods: This study leveraged IDD data from the FinnGen R12 cohort and integrated expression quantitative trait loci data across 49 tissues from the Genotype-Tissue Expression version 8 database to perform a cross-tissue transcriptome-wide association study (TWAS).

Lower back pain caused by intervertebral disk degeneration (IDD) is a common problem among middle-aged and older adults. We aimed to identify novel diagnostic biomarkers of IDD and analyze the potential association between key genes and immune cell infiltration. We screened differentially expressed genes (DEGs) related to IDD and gene sets associated with mitochondrial energy metabolism using the Gene Expression Omnibus and GeneCards databases, respectively.

Lycium barbarum is a traditional Chinese medicine that has been demonstrated to exhibit a wide variety of biological functions, such as antioxidation, neuroprotection, and immune modulation. The therapeutic effect of Lycium barbarum on intervertebral disc degeneration (IVDD) has not been conclusively established. In our study, we investigated the mechanisms of Lycium barbarum extract (LBE) using Network pharmacology and bioinformatic analyses.

Pug dogs are predisposed to thoracolumbar myelopathy associated with vertebral articular process dysplasia, suggesting a biomechanical etiology. While surgery is commonly pursued, long-term outcomes remain poorly defined. This retrospective descriptive case series reports on seven Pug dogs that underwent surgical treatment for thoracolumbar myelopathy and were followed up for at least 7 years postoperatively.
