| Outline of Final Research Achievements |
For the preparation of more potent periosteal sheets, we examined the applicability of stem-cell culture medium. Periosteal sheets expanded with stem-cell culture medium, and formed thicker multilayers of cells. During this process, the surface marker CD146 was substantially upregulated. A representative osteoblastic marker, alkaline phosphatase was not upregulated by osteogenic induction. However, these expanded periosteal sheets exhibited substantially stronger osteogenic differentiation when implanted in nude mice. With respect of the effect of these expanded periosteal sheets on angiogenesis, we examined by using the experimental design such as implantation to mice or chorioallantoic membrane model (CAM) assay. In the latter experiment, angiogenesis and neovascularization was significantly increased. Moreover, the complex of the expanded periosteal sheets with human umbilical vein endothelial cells (HUVECs) has not been revealed a cooperative response.
