Osteoarthritis is the most common degenerative disease of joints like the hip and the trapeziometacarpal joint (rhizarthrosis). In this in vitro study, we compared the chondrogenesis of chondrocytes derived from the trapezium and the femoral head cartilage of osteoarthritic patients to have a deeper insight on trapezium chondrocyte behavior as autologous cell source for the repair of cartilage lesions in rhizarthrosis. Chondrocytes collected from trapezium and femoral head articular cartilage were cultured in pellets and analyzed for chondrogenic differentiation, cell proliferation, glycosaminoglycan production, gene expression of chondrogenic and fibrous markers, histological and immunohistochemical analyses. Our results showed a higher cartilaginous matrix deposition and a lower fibrocartilaginous phenotype of the femoral chondrocytes with respect to the trapezium chondrocytes assessed by a higher absolute glycosaminoglycan and type II collagen production, thus demonstrating a superior chondrogenic potential of the femoral with respect to the trapezium chondrocytes. The differences in chondrogenic potential between trapezium and femoral head chondrocytes confirmed a lower regenerative capability in the trapezium than in the femoral head cartilage due to the different environment and loading acting on these joints that affects the metabolism of the resident cells. This could represent a limitation to apply the cell therapy for rhizoarthrosis.

Abstract

Osteoarthritis is the most common degenerative disease of joints like the hip and the trapeziometacarpal joint (rhizarthrosis). In this in vitro study, we compared the chondrogenesis of chondrocytes derived from the trapezium and the femoral head cartilage of osteoarthritic patients to have a deeper insight on trapezium chondrocyte behavior as autologous cell source for the repair of cartilage lesions in rhizarthrosis. Chondrocytes collected from trapezium and femoral head articular cartilage were cultured in pellets and analyzed for chondrogenic differentiation, cell proliferation, glycosaminoglycan production, gene expression of chondrogenic and fibrous markers, histological and immunohistochemical analyses. Our results showed a higher cartilaginous matrix deposition and a lower fibrocartilaginous phenotype of the femoral chondrocytes with respect to the trapezium chondrocytes assessed by a higher absolute glycosaminoglycan and type II collagen production, thus demonstrating a superior chondrogenic potential of the femoral with respect to the trapezium chondrocytes. The differences in chondrogenic potential between trapezium and femoral head chondrocytes confirmed a lower regenerative capability in the trapezium than in the femoral head cartilage due to the different environment and loading acting on these joints that affects the metabolism of the resident cells. This could represent a limitation to apply the cell therapy for rhizoarthrosis.
