Intervertebral disk degeneration is a common disease with an unknown etiology. Currently, tissue engineering is considered to be an important method for intervertebral disk repair. Although transplanted stem cells may disrupt the repair process because of apoptosis caused by the oxidative microenvironment. Herein, bone marrow mesenchymal stem cell (BMSC) and Neochlorogenic acid (Ncg) were encapsulated into a GelMA hydrogel as a carrier to protect transplanted stem cells. Ncg effectively inhibited the oxidative stress process and reduced the apoptosis rate. A 5% GelMA hydrogel had a large pore size and porosity that provided an enhanced survival space for cells. An in vivo assessment showed that treatment with GelMA + BMSC + Ncg produced greater repair of degenerated intervertebral disks than that found in other model groups. Thus, this study may help contribute to improving stem cell transplantation for treating intervertebral disk degeneration.

Objectives: A thorough understanding of common practice patterns in a particular specialty can help identify and design new interventions to improve care delivery and access to care. The goals of this study were to document current practice patterns among veterinary "neurologists" and small animal "surgeons" in the surgical management of acute canine thoracolumbar intervertebral disc extrusion, to compare approaches between these two groups and to discuss current results compared to those published in 2016.
Materials And Methods: A web-based survey was distributed in October 2024 to collect responses from board-certified and regionally recognised neurology and surgery specialists in North America and Europe.

Introduction: While nucleus pulposus cell (NPC) degeneration is a primary driver of intervertebral disc degeneration (IVDD), the cellular heterogeneity and molecular interactions underlying NPC degeneration remain poorly characterized. Previous studies have shown that EGFR signaling plays a significant role in NPC differentiation and collagen matrix production. Consequently, this study aims to identify the critical downstream regulatory molecule of EGFR in the process of NPC degeneration.

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.
