Histological Analysis of Failed Cartilage Repair after Marrow Stimulation for the Treatment of Large Cartilage Defect in Medial Compartmental Osteoarthritis of the Knee [PDF]

open access: yes, 2013
Bone marrow-stimulating techniques such as microfracture and subchondral drilling are valuable treatments for full-thickness cartilage defects. However, marrow stimulation-derived reparative tissues are not histologically well-documented in human ...

Collagen-induced Arthritis: A Model for Murine Autoimmune Arthritis

open access: yesBio-Protocol, 2015
Collagen-induced arthritis (CIA) is a common autoimmune animal model used to study rheumatoid arthritis (RA). The development of CIA involves infiltration of macrophages and neutrophils into the joint, as well as T and B cell responses to type II ...

Early detection of osteoarthritis in the rat with an antibody specific to type II collagen modified by reactive oxygen species

open access: yesArthritis Research & Therapy, 2021
Background Osteoarthritis (OA) is a disease of the whole joint, with articular cartilage breakdown as a major characteristic. Inflammatory mediators, proteases, and oxidants produced by chondrocytes are known to be responsible for driving cartilage ...

Transcriptional inhibition of type I collagen gene expression in scleroderma fibroblasts by the antineoplastic drug ecteinascidin 743. [PDF]

open access: yes, 2003
We previously showed that COL1A1 expression is up-regulated at the transcriptional level in systemic sclerosis (SSc) fibroblasts and that the CCAAT-binding factor (CBF) is involved in this increased expression.

Comparative Effectiveness of Structural versus Regulatory Protein Gene Transfer on Articular Chondrocyte Matrix Gene Expression [PDF]

open access: yes, 2019
OBJECTIVE: The production of extracellular matrix is a necessary component of articular cartilage repair. Gene transfer is a promising method to improve matrix biosynthesis by articular chondrocytes.

Efficacy and safety of native type II collagen in modulating knee osteoarthritis symptoms: a randomised, double‐blind, placebo‐controlled trial

open access: yesJournal of Experimental Orthopaedics, 2022
Purpose Knee osteoarthritis (OA) is the most common form of clinical arthritis in middle‐aged and older individuals. Undenatured or native type II (TII) collagen derived from the chicken sternum has a good therapeutic effect on relieving severe pain of ...

Categorization of collagen type I and II blend hydrogel using multipolarization SHG imaging with ResNet regression

open access: yesScientific Reports, 2023
Previously, the discrimination of collagen types I and II was successfully achieved using peptide pitch angle and anisotropic parameter methods. However, these methods require fitting polarization second harmonic generation (SHG) pixel-wise information ...

Recessive osteogenesis imperfecta caused by LEPRE1 mutations: clinical documentation and identification of the splice form responsible for prolyl 3-hydroxylation [PDF]

open access: yes, 2009
: Background: Recessive forms of osteogenesis imperfecta (OI) may be caused by mutations in LEPRE1, encoding prolyl 3-hydroxylase-1 (P3H1) or in CRTAP, encoding cartilage associated protein.
