circNR3C2 promotes chondrogenic differentiation and cartilage repair of human adipose‐derived stem cells via the hsa‐miR‐647/SOX9 pathway

Animal Models and Experimental Medicine, EarlyView.
The hypothesis diagram illustrates the function and mechanism of circNR3C2: circNR3C2 overexpression can up‐regulate COL2, Aggrecan and SOX9 expression, and regulate chondrogenic differentiation of hADSCs by targeting hsa‐miR‐647. Abstract Background Human adipose‐derived stem cells (hADSCs) are seed cells with application prospects in cartilage repair.

Optimizing biophysical properties of cellular niches to enhance stem cell‐derived extracellular vesicle function in musculoskeletal regeneration

BMEMat, EarlyView.
Extracellular vesicles (EVs) derived from stem cells show promise for applications in regenerative medicine, but their scalability and yield remain challenges. This review explores the approaches for biophysical modulations within cell niches on EV properties, discusses the current clinical application of EVs, and provides an outlook on the existing ...

Leptin downregulates aggrecan through the p38-ADAMST pathway in human nucleus pulposus cells. [PDF]

PLoS ONE, 2014
The mechanistic basis of obesity-associated intervertebral disc degeneration (IDD) is unclear. Aberrant expression of aggrecan and its degrading enzymes ADAMTS-4 and ADAMTS-5 is implicated in the development of IDD.

Histopathologic Analysis of the Morpho‐Functional Zones of the Human Acetabular Labrum

Clinical Anatomy, EarlyView.
ABSTRACT The structural and functional adaptation of soft tissues to mechanical load controls their ability to withstand injury and influences their capacity for healing. Similar to the knee meniscus, the acetabular labrum exhibits zonal differences in mechanical load distribution, resulting in distinct regions with unique structural and functional ...

Periodontitis treatment and microbiome in a patient with FAM20A mutation: Case study of 1.5 years

Clinical Advances in Periodontics, EarlyView.
Abstract Background Enamel‐renal‐gingival syndrome (ERGS) is an autosomal recessive disorder caused by mutations in the FAMily with sequence similarity 20A (FAM20A) gene, and is characterized by amelogenesis imperfecta, delayed or failed tooth eruption, and periodontitis.

A two‐sample Mendelian randomization study and mediation analysis exploring the link between cathepsins and epilepsy

Epilepsia Open, EarlyView.
Abstract Objective This study aims to investigate the causal relationship between cathepsins and epilepsy, using Mendelian randomization (MR) and mediation analysis. Methods Publicly accessible summary statistics on epilepsy were obtained from FinnGen and the International League Against Epilepsy Consortium.

Injectable Biomimetic Composite Hydrogel Scaffold With Tissue‐Engineered Cartilage Matrix for Articular Cartilage Regeneration

Rare Metals, EarlyView.
ABSTRACT Articular cartilage regeneration remains a significant challenge because of its limited intrinsic healing capacity and the inadequacy of conventional treatments for restoring structural and functional integrity. In this study, a novel injectable composite hydrogel scaffold was designed to mimic the extracellular matrix (ECM) of native ...

Mechanical compression induces chondrocyte hypertrophy by regulating Runx2 O-GlcNAcylation during temporomandibular joint condyle degeneration

Bone & Joint Research
Aims: Excessive chondrocyte hypertrophy is a common feature in cartilage degeneration which is susceptible to joint overloading, but the relationship between mechanical overloading and chondrocyte hypertrophy still remains elusive.
