Abstract Osteoarthritis (OA), a progressive degenerative disease of cartilage in joints, is the most common cause chronic disability older adults. While OA mostly considered an age-related pathology, women have 1.5-fold higher risk developing relative to men and experience more severe symptoms. Yet, they remain underrepresented musculoskeletal research clinical trials. Responsible for formation...
INTRODUCTION Cartilage degeneration driven by catabolic stimuli is a critical pathophysiological process in osteoarthritis (OA). We have defined fibroblast growth factor 2 (FGF-2) as a degenerative mediator in adult human articular chondrocytes. Biological effects mediated by FGF-2 include inhibition of proteoglycan production, up-regulation of matrix metalloproteinase-13 (MMP-13), and stimulat...
OBJECTIVE To determine the role of progressive ankylosis protein (ANK)/Myb-binding protein 1a (MYBBP1a) and sphingosine kinase 1 (SPHK1) interactions in catabolic events of articular chondrocytes. METHOD ANK/MYBBP1a and SPHK1 interactions were identified using yeast two-hybrid screening and co-immunoprecipitation. To determine the role of these interactions in catabolic events of articular ch...
Resveratrol is a natural polyphenolic compound that prevents inflammation in chondrocytes and animal models of osteoarthritis (OA) via yet to be defined mechanisms. The purpose of this study was to determine whether the protective effect of resveratrol on IL-1β-induced human articular chondrocytes was associated with the TLR4/MyD88/NF-кB signaling pathway by incubating human articular chondrocy...
The newly evolved field of regenerative medicine is offering solutions in the treatment of bone or cartilage loss and deficiency. Mesenchymal stem cells, as well as articular chondrocytes, are potential cells for the generation of bone or cartilage. The natural mechanism of bone formation is that of endochondral ossification, regulated, among other factors, through the hormones dexamethasone an...
OBJECTIVE To clarify the effect of interleukin (IL) 18 on cartilage degeneration by studying the profile of IL18 receptor (IL18R) on chondrocytes and the direct effect of IL18 on production of matrix metalloproteinases (MMPs), aggrecanases, and tissue inhibitors of metalloproteinases (TIMPs) in articular chondrocytes. METHODS Monolayer cultured human articular chondrocytes were isolated from ...
Resveratrol, a naturally occurring polyphenolic phytoalexin antioxidant compound present in grapes and red wine, has been reported to induce various biochemical responses. It has been shown to possess anti-aging, anti-inflammatory and anti-proliferative activities in several cell types. However, the effects of resveratrol in normal cells, including chondrocytes, have not yet been clearly elucid...
Objective: To clarify the effect of interleukin (IL) 18 on cartilage degeneration by studying the profile of IL18 receptor (IL18R) on chondrocytes and the direct effect of IL18 on production of matrix metalloproteinases (MMPs), aggrecanases, and tissue inhibitors of metalloproteinases (TIMPs) in articular chondrocytes. Methods: Monolayer cultured human articular chondrocytes were isolated from ...
Mesenchymal stem cell (MSC)-based cell therapy is a promising avenue for osteoarthritis (OA) treatment. In the present study, we evaluated the efficacy of intra-articular injections of culture-expanded allogenic adipose tissue-derived stem cells (ADSCs) for the treatment of anterior cruciate ligament transection (ACLT) induced rat OA model. The paracrine effects of major histocompatibility comp...
Synovial joints and articular cartilage play crucial roles in the skeletal function, but relatively little is actually known about their embryonic development. Here we first focused on the interzone, a thin mesenchymal cell layer forming at future joint sites that is widely thought to be critical for joint and articular cartilage development. To determine interzone cell origin and fate, we micr...
