Abstract

Articular cartilage extracellular matrix (ECM) plays a crucial role in regulating chondrocyte functions via cell-matrix interaction, cytoskeletal organization and integrinmediated signaling. The effects of transforming growth factor- β (TGF- β) and β –estradiol on extracellular matrix have remained controversial in chondrocyte studies though it has been proven that cartilage responds to these factors in vivo. In our study, we examined the effect of these factors on modulating glycosaminoglycan secretion. Articular chondrocytes from rabbits were cultured, and the effects of supplementing 10ng/ml of TGF- β, 10nM of β -estradiol, and a combination of both factors were compared. The synthesis of sulphated glycosaminoglycan (GAG) was shown to be enhanced in the TGF- β treated cultures and when TGF-β and β -estradiol were both used. However, β -estradiol does not appear to affect GAG deposition.
