Method for inducing differentiation from the pulp cells into odontoblasts

The present invention, that the efficient pulp cells provides a method for inducing differentiation into odontoblasts and challenges, further provides efficiently odontoblast to differentiate inducible-inducing agents. The Wnt signaling pathway by using a activated can material, by the differentiation inducing method of the pulp cells into odontoblasts. Further, by differentiation inducer comprising a substance capable of activating the Wnt signaling pathway. Specifically, sodium perchlorate, sodium perchlorate, either by being selected from lithium chloride, from Norrin and R-Spondin2.
