Mechanosensitive Cell‐Laden Shape‐Memory Scaffolds Engineered via Cryogelation

Small Structures, EarlyView.
GelMA‐based shape‐memory scaffolds encapsulating human adipose‐derived stem cells are fabricated via cryogelation, showing rapid recovery and high cell viability. Under cyclic compression, they promoted mechanotransduction gene expression, and composite formulations (collagen/GelMA, dECM/GelMA) retained robust shape‐memory, highlighting their promise ...

Intervertebral Disc Degeneration and Regeneration: New Molecular Mechanisms and Therapeutics

Cells
The intervertebral disc (IVD) is a soft tissue that constitutes the spinal column together with the vertebrae, and consists of the central nucleus pulposus (gelatinous tissue) and the annulus fibrosus (rich in fibrous tissue) that surrounds the nucleus ...

Comparison of Adjacent Segment Degeneration After Nonrigid Fixation System and Posterior Lumbar Interbody Fusion for Single-Level Lumbar Disc Herniation: A New Method of MRI Analysis of Lumbar Nucleus Pulposus Volume

Journal of Investigative Surgery, 2018
Purpose: To evaluate the influence of a nonrigid fixation system and posterior lumbar interbody fusion on adjacent intervertebral disc degeneration by using MRI analysis of lumbar nucleus pulposus volume for single-level lumbar disc herniation. Materials

Axial length, myopia progression, and myopic maculopathy in Stickler syndrome

Acta Ophthalmologica, EarlyView.
Abstract Purpose We lack knowledge on the potentially progressive nature of and the prevalence of complications to myopia as a characteristic trait of Stickler syndrome. Methods This cross‐sectional study combines ophthalmic examination and medical record data on Danish patients with genetically confirmed Stickler syndrome type 1 (COL2A1) and type 2 ...

Fibro-NPC: a pathogenic subtype identified at single-cell resolution with secreted SFRP4 as a biomarker in intervertebral disc degeneration

Journal of Translational Medicine
Background Intervertebral disc degeneration (IDD) is a primary cause of low back pain and, in severe cases, can lead to disability. Current treatments for low back pain remain limited in efficacy, underscoring the need for a deeper understanding of the ...

The tandem–random transition of cellular patterning: proposed roles of N‐cadherin‐based orientational cell adhesions in the development, maintenance, and degeneration of the nucleus pulposus

Biological Reviews, EarlyView.
ABSTRACT Intervertebral disc degeneration (IDD) can contribute to lower back and neck pain. In IDD, the most affected component of the intervertebral disc is the nucleus pulposus (NP). Derived from the notochord, where cells are organized into a tandem configuration, young NP cells cluster in three‐dimensional (3D) networks embedded in a gelatinous ...

Knockdown of miR-660 protects nucleus pulposus cells from TNF-a-induced apoptosis by targeting serum amyloid A1

Journal of Orthopaedic Surgery and Research, 2020
Background Intervertebral disc degeneration (IVDD) is a well-known cause of lower back pain, which is induced by multiple factors including increased apoptosis and decreased survival of nucleus pulposus cells.

Propionibacterium acnes evades microbicidal phagocytosis by inhibiting the mitochondrial biogenesis of nucleus pulposus cells

The FEBS Journal, EarlyView.
P. acnes infection impairs the mitochondrial biogenesis of nucleus pulposus cells (NPCs) through the AMPK/SIRT‐1/PGC‐1α signaling pathway. This results in impaired mitochondria that are unable to generate sufficient ATP, and impaired delivery of mitochondrial reactive oxygen species to carry out the bactericidal process effectively.

Newly identified intervertebral fat pad degenerates after intervertebral disc injury in a rat model of degeneration

Journal of Anatomy, EarlyView.
This study characterizes a newly‐described intervertebral fat pad (IVFP) anterior to rat IVDs, with evidence for its existence in mice and human IVDs as well. In rats, the IVFP gradually degenerated following IVD injury with changes in adipocyte size and fibrous tissue infiltration, suggesting it could play a functional role in IVD health and ...
