| Outline of Final Research Achievements |
The specific hypothesis of this study is that bone marrow-derived endothelial progenitor cells (CD34-positive cells) can rescue the radiogenic salivary-gland atrophy. Furthermore, we assumed that the delivery of functional miRNA that contributes the proliferation or differentiation of salivary-gland epithelial cells may be able to enhance the effect of CD34-positive cell therapy. As a result, local administration of CD34-positive cells to submandibular glands could increase the salivary output of mice after 12Gy of head and neck irradiation. Currently, we are analyzing in vivo behavior of exogenous CD34-positive cells in detail, and administrating miRNAs with CD34-positive cells to irradiated mice.
