Biochemical and biophysical properties of cartilage: In Vitro Models for Cartilage Repair.

Cartilage consists mainly of sparsely distributed cells embedded in a matrix composed of highly negatively charged proteoglycans (PGs) entrapped within a collagen network, a feature that is important in establishing the biomechanical properties of the tissue.

The ability of cartilage to repair itself after mechanical injury or degradation is limited and recently several techniques have been devised to promote cartilage repair. However, in most techniques the newly synthesised matrix has biochemical and biomechanical properties different to those found in the tissue of origin. The aim of these studies is to devise optimum conditions to promote cartilage repair "in vitro" and "in vivo".

Characterisation of proteoglycans in the endometrium.

Steroid hormones are known to influence the composition of the extracellular matrix of their target organs. One of the most noticeable changes in response to fluctuating hormonal levels is the degree of hydration of the tissue which is attributed to alterations in glycosaminoglycan content.

We have characterised proteoglycans in the ovine endometrium during the proliferative and secretory phases and have established that one of the glycosaminoglycans, hyaluronan, plays an important role in the composition of the extracellular matrix.

We are currently investigating expression patterns of the enzymes involved in the synthesis and degradation of hyaluronan in the cycling human endometrium. These studies will provide a better understanding of the role of the extracellular matrix in preparing the endometrium for implantation.

Functional effects of antibodies to collagen on cartilage synthesis and degradation.

It has been suggested that an antibody response to critical determinants of articular cartilage, particularly collagen II, is an essential causal component in rheumatoid arthritis, as for the animal model collagen-induced arthritis.

The aim of these studies is to test whether mouse monoclonal antibodies of defined specificity and a demonstrated capacity to transfer arthritis in vivo can impair synthesis and/or degradation of cartilage in chondrocyte cultures and in cartilage explants cultures.
