N2 - The objective of this study was to identify the mechanism by which mandibular condyle chondrocytes regulate the extracellular matrix. Primary rabbit condylar chondrocytes were isolated, cultured, and treated with transforming growth factor beta 1 (TGF-β1). Cells were then assayed for the following: urokinase-type plasminogen activator (uPA) and its inhibitor (PAI-1), collagen types I and II, β1 integrin expression, and proliferative activity. TGF-β1 induced synthesis of collagen type II, αVβ1 integrin, and PAI-1. TGF-β1 induced the growth of chondrocytes and suppressed the synthesis of uPA. Chondrocyte regulation of the extracellular matrix is mediated by TGF-β1. Synthesis of collagen type II, αVβ1 integrin, and PAI-1 is induced, while uPA is suppressed. Also, TGF-β1 induces cellular growth.
