Abstract
A method and composition are provided for inducing or enhancing chondrogenesis in vivo or in vitro. The method is performed by exposing the cells in vitro or in vivo to an extracellular matrix comprising of type I collagen, type II collagen or a mixture of type I collagen or type II collagen and hyaluronate and further containing GDF-5.
Claims4
A method for inducing chondrogenesis in vivo in joint tissue cells comprising the step of exposing said cells to a matrix composition comprising type I collagen, hyaluronate and growth and differentiation factor-5.
A method for inducing chondrogenesis in vivo in joint tissue cells comprising the step of exposing said cells to a matrix composition comprising type II collagen, hyaluronate and growth and differentiation factor-5.
A composition comprising an extracellular matrix of type I collagen and hyaluronate, said matrix containing an effective amount of growth and differentiation factor-5 sufficient to induce chondrogenesis in vivo in joint tissue cells.
A composition comprising an extracellular matrix of type II collagen and hyaluronate, said matrix containing an effective amount of growth and differentiation factor-5 sufficient to induce chondrogenesis in vivo in joint tissue cells.
