Endogenous Complement Factor H Plays an Important Role in Controlling Immune Complex-Induced Inflammatory Arthritis
Background/Purpose: The complement system, a major component of innate immunity, likely plays an important role in the pathogenesis of rheumatoid arthritis (RA). Factor H (fH)…Abstract Number: 11 • 2012 ACR/ARHP Annual Meeting

Background/Purpose: The aim of this study was to obtain cartilage-like constructs by chondrogenic differentiation of human bone marrow mesenchymal stem cells (hBM-MSCs) grown on different…Abstract Number: 1019 • 2012 ACR/ARHP Annual Meeting
Visualization of Cartilage in High-Resolution Magnetic Resonance Imaging Is a New Imaging Biomarker for the Quantification of Joint Damage in Rheumatoid Arthritis
Background/Purpose: Recent achievements in Magnetic Resonance Imaging (MRI) have been the gradient-echo-based T1-delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) focussing on the detection of proteoglycan content…Abstract Number: 12 • 2012 ACR/ARHP Annual Meeting
Articular Cartilage Expresses the IL-15 Receptor Alpha-Chain and Responds to IL-15 with Increased Matrix Metalloproteinase Release
Background/Purpose: IL-15, known for its effects on survival of lymphocyte subsets, plays a role in synovitis of Rheumatoid Arthritis. We reported that IL-15 is also…Abstract Number: 1027 • 2012 ACR/ARHP Annual Meeting
Frequency of MRI-Detected Hip Osteoarthritis Features in Persons with Chronic Hip Pain and the Diagnostic Performance of Radiography Using MRI As the Reference
Background/Purpose: Conventional radiography has been the standard imaging tool to diagnose and grade the severity of hip OA. However, radiography cannot visualize the bone marrow,…Abstract Number: 17 • 2012 ACR/ARHP Annual Meeting
Synovial Overexpression of Wnt and Wnt-1-Induced Secreted Protein 1 Induces Cartilage Damage by Skewing of TGF-Beta Signaling and Reduction of the Anti-Hypertrophy Factor Sox9
Background/Purpose: Although many osteoarthritis (OA) patients show significant synovial involvement, consequences are largely unknown. We found highly increased expression of canonical Wnts 2b and 16…Abstract Number: 1029 • 2012 ACR/ARHP Annual Meeting
Frequency of Mediopatellar Plica in Persons with Chronic Knee Pain and Its Cross-Sectional Association with Patellofemoral Cartilage Damage and Bone Marrow Lesions: Data From the Joints On Glucosamine Study
Background/Purpose: Osteoarthritis (OA) commonly occurs in the patellofemoral joint (PFJ) and knee pain in subjects with knee OA often emanates from the PFJ rather than…Abstract Number: 19 • 2012 ACR/ARHP Annual Meeting
Stress-Induced Cartilage Degradation Does Not Depend On NLRP3-Inflammasome in Osteoarthritis
Background/Purpose: The cartilage matrix breakdown in osteoarthritis (OA) is due to both abnormal mechanical stress and activation of catabolic processes involving metalloproteinases (MMPs). Currently, IL-1beta…Abstract Number: 988 • 2012 ACR/ARHP Annual Meeting
Zone-Specific Protein Profiles in Human Cartilage Unraveled by a Quantitative Proteomic Approach
Background/Purpose: Articular cartilage consists of a single type of cells called chondrocytes, which comprise 2-5% of total tissue mass and an extracellular matrix (ECM) mainly…Abstract Number: 22 • 2012 ACR/ARHP Annual Meeting
Protective Properties of Conditioned Media From Adipose Stem Cells On Osteoarthritic Chondrocytes
Background/Purpose: Adipose-derived mesenchymal stem cells (ASC) exhibit a high potential for cell therapy and they might also act as a cellular source for supplying soluble…Abstract Number: 993 • 2012 ACR/ARHP Annual Meeting
A Genome-Wide DNA Methylation Analysis Reveals Different Methylation Patterns in the OA Disease
Background/Purpose: DNA methylation is a basic mechanism involved in epigenetic regulation that affects gene transcription by the addition of a methyl group to the cytosine…Abstract Number: 25 • 2012 ACR/ARHP Annual Meeting
Activation of the Canonical Wnt Signaling Pathway Is Tissue Dependent in Osteoarthritic Joints: Distinct Mechanisms of Regulation by Wnt Antagonists
Background/Purpose: Wnt signaling pathway is a major regulator of bone and cartilage remodeling. Modulation of this pathway has lead to controversial results on joint cartilage…Abstract Number: 994 • 2012 ACR/ARHP Annual Meeting
The Genome-Wide Expression of Human Osteoarthritic Cartilage Shows A Differential Pattern Between Two Subgroups of OA Patients
