| Research Abstract |
Dental pulp cells are differentiate into odontoblasts, which are dentin-forming cells, and osteoblasts are bone tissue-forming cells. These cells are categorized as hard tissue forming cells, and may possess common properties. Mineralization of these cells in the conventional two dimensional culture is only observed in the presence of mineralization-inducing factors, such as BMPs or ascorbic acid and beta-glycerophosphate. We revealed that three dimensional (3-D) culture induced up-regulation of odonto-/osteo-blast marker expression in dental pulp cells and osteoblasts. Transplantation of 3-D cultured pulp cells or osteoblasts into bone cavities effectively induced hard tissue formation. Clinical application of 3-D cultured dental pulp cells or osteoblasts are expected.
