| Research Abstract |
Dental pulp cells are considered to be a promising tool for the regeneration of hard tissues, due to their multipotency. Mouse dental pulp cells exhibited strong alkaline phosphatase and extracellular matrix calcification activity even in the absence of exogenous rhBMP-2.The transplanted dental pulp cells into immunodeficiency mice exert bone regenerative activity in vivo. In addition, human dental pulp cells also exhibited strong alkaline phosphatase and extracellular matrix calcification activity.
