Provided is a method for regenerating dental tissue, which can include contacting a scaffold containing Wnt3a and BMP-7, and optionally VEGF, bFGF, or NGF, with a dental tissue so as to promote odontoblastic differentiation of a progenitor cell, promote progenitor cell migration into the dental tissue, or regenerate the dental tissue. Also provided is a composition for regeneration of dental tissue, which can include a scaffold and Wnt3a and BMP-7, and optionally VEGF, bFGF, or NGF.
