In Situ Profiling of Nanoscale Strains Uncovers Mechano‐Architectural Predictors of Aging and Osteoarthritis Emergence

Advanced Science, EarlyView.
In situ mechanical loading of osteoarthritis‐prone murine knee joints reveals that spatial alterations in subchondral plate microarchitecture precede cartilage loss and promote a shift from coordinated epiphyseal strain dissipation in healthy joints to focal subchondral strain concentration in osteoarthritis‐prone joints.

Regulation of chondrocyte hypertrophy in an osteochondral interface mimicking gel matrix

Colloids and Surfaces B: Biointerfaces, 2020
Calcified cartilage extracellular matrix (ECM) is a critical interface at the osteochondral junction which plays an important role in maintaining the structural continuity between articular cartilage and subchondral bone. This mineralized network is primarily composed of glycosaminoglycans (GAGs) and collagen type II (col II) and hosts hypertrophic ...

Synergistic co-regulation and competition by a SOX9-GLI-FOXA phasic transcriptional network coordinate chondrocyte differentiation transitions. [PDF]

PLoS Genetics, 2018
The growth plate mediates bone growth where SOX9 and GLI factors control chondrocyte proliferation, differentiation and entry into hypertrophy. FOXA factors regulate hypertrophic chondrocyte maturation.

Dual‐Scaffold Technique: Autologous Minced Cartilage and Bone Marrow Aspirate Scaffold Combined With Synthetic Collagen Membrane for Cartilage Repair

Arthroscopy Techniques, EarlyView.
Abstract Treating cartilage injuries has long been a complex challenge; however, recent progress has greatly increased the variety of effective therapeutic approaches. The minced autologous matrix‐induced chondrogenesis plus procedure for full‐thickness knee cartilage lesions uses a collagen matrix combined with shaver‐minced cartilage graft and bone ...

Neurovascular coupling in bone regeneration: Mechanisms, advanced biomaterials and challenges

BMEMat, EarlyView.
This figure illustrates various material strategies for neurovascularized bone regeneration, including electroactive scaffolds, ion‐loaded materials, drug delivery systems, surface modifications, cells/cell products, growth factors, and peptides. These approaches aim to synergistically promote the regeneration of neural, vascular, and bone tissues ...

Identification and characterization of up-regulated genes during chondrocyte hypertrophy [PDF]

Developmental Dynamics, 1996
Chondrocyte hypertrophy involves de novo acquisition and/or increased expression of certain gene products including, among others, type X collagen, alkaline phosphatase, and matrix metalloproteinases. To analyze further the genetic program associated with chondrocyte hypertrophy, we have employed a modification of the polymerase chain reaction-mediated

Transcription Factors in Cartilage Homeostasis and Osteoarthritis

Biology, 2020
Osteoarthritis (OA) is the most common degenerative joint disease, and it is characterized by articular cartilage loss. In part, OA is caused by aberrant anabolic and catabolic activities of the chondrocyte, the only cell type present in cartilage. These

Suppression of Hypertrophy During in vitro Chondrogenesis of Cocultures of Human Mesenchymal Stem Cells and Nasal Chondrocytes Correlates With Lack of in vivo Calcification and Vascular Invasion

Frontiers in Bioengineering and Biotechnology, 2021
ObjectiveHuman nasal septal chondrocytes (NC) are a promising minimally invasive derivable chondrogenic cell source for cartilage repair. However, the quality of NC-derived cartilage is variable between donors. Coculture of NC with mesenchymal stem cells

Mechanism study of an articular cartilage repair material and its forward‐looking test for space medicine

BMEMat, EarlyView.
The regeneration process following dLhCG engraftment progressed through four distinct and interconnected stages. dLhCG maintained its regenerative efficacy after 6 months of cosmic exposure, supporting its potential application in space medicine.

Activation of mTORC1 in chondrocytes does not affect proliferation or differentiation, but causes the resting zone of the growth plate to become disordered

Bone Reports, 2018
There are several pitfalls associated with research based on transgenic mice. Here, we describe our interpretation and analysis of mTORC1 activation in growth plate chondrocytes and compare these to a recent publication (Yan et al., Nature Communications
