Multimaterial Triphasic Scaffold Replicates Enthesis Microenvironment to Modulate Early Cell Responses

open access: yesAdvanced NanoBiomed Research, EarlyView.
A bioinspired triphasic scaffold integrating 3D printed polycaprolactone and electrospun poly(lactic‐co‐glycolic acid) is developed to replicate the organization of the tendon‐to‐bone enthesis. Cyclic mechanical stimulation induces spatially defined cell morphology and lineage‐related gene expression in human mesenchymal stem cells, highlighting the ...

Aggrecan: A target molecule of autoimmune reactions

open access: yesPathology & Oncology Research, 1996
Aggrecan in cartilage forms aggregates with hyaluronan and link protein, embedded in a collagen network. It accounts for the compressive stiffness and resilience of the hyaline cartilage. Many forms of inflammatory arthritis were shown to be accompanied with aggrecan degradation and loss from the cartilage. The loss of this major component of cartilage

Osteocyte dysfunction promotes osteoarthritis through MMP13-dependent suppression of subchondral bone homeostasis. [PDF]

open access: yes, 2019
Osteoarthritis (OA), long considered a primary disorder of articular cartilage, is commonly associated with subchondral bone sclerosis. However, the cellular mechanisms responsible for changes to subchondral bone in OA, and the extent to which these ...

RNA Sequencing Reveals a Role of TonEBP Transcription Factor in Regulation of Pro-inflammatory Genes in Response to Hyperosmolarity in Healthy Nucleus Pulposus Cells: A HOMEOSTATIC RESPONSE? [PDF]

open access: yes, 2016
Transcription factor tonicity-responsive enhancer-binding protein (TonEBP/NFAT5) is critical for osmo-adaptation and extracellular matrix homeostasis of nucleus pulposus (NP) cells in their hypertonic tissue niche.

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

open access: yesClinical 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 ...
