Abstract:
1. A plurality of teeth, obtained by positioning a first cell mass substantially containing only either one of mesenchymal cells or epithelial cells, wherein at least one of the mesenchymal cells or the epithelial cells is derived from one tooth germ, and a second cell mass substantially containing only the other one of the mesenchymal cells or the epithelial cells, inside a support carrier, such that the first and the second cell masses are in a state of close contact with each other inside the support carrier without mixing between the cell masses, wherein the mesenchymal cells or the epithelial cells are in close contact with each other in the corresponding cell mass; positioning the first cell mass inside the support carrier such that the second cell mass makes a depression in the first cell mass such that the first cell mass substantially envelops the second cell mass when the second cell mass is inserted into the support carrier; and culturing the first and the second cell masses inside the support carrier until the plurality of teeth is formed, while maintaining the state of close contact between the cell masses.
