Suppression of MMP activity in bovine cartilage explants cultures has little if any effect on the release of aggrecanase-derived aggrecan fragments

Progressive loss of articular cartilage is a central hallmark in many joint disease, however, the relative importance of individual proteolytic pathways leading to cartilage erosion is at present unknown. We therefore investigated the time-dependant release ex vivo of MMP- and aggrecanase-derived fr…

Identification of progressors in osteoarthritis by combining biochemical and MRI-based markers

INTRODUCTION:
At present, no disease-modifying osteoarthritis drugs (DMOADS) are approved by the FDA (US Food and Drug Administration); possibly partly due to inadequate trial design since efficacy demonstration requires disease progression in the placebo group. We investigated whether combinations…

Cartilage formation measured by a novel PIINP assay suggests that IGF-I does not stimulate but maintains cartilage formation ex vivo

OBJECTIVES:
The aim of this study was to investigate the time-dependent effect of insulin-like growth factor-I (IGF)-I on cartilage, evaluated by a novel procollagen type II N-terminal propeptide (PIINP) formation assay. This was performed in a cartilage model.

METHODS:
Bovine articular cartila…
