| Outline of Final Research Achievements |
It is said that there are cells capable of reconstructing it in the cancer tissue (cancer stem cells), and a cancer tissue as a hierarchical cell group is constructed. In order to develop a reagent for cancer stem cell imaging, fluorescent dye-encapsulated liposome coated with marker of brain tumor and colon cancer stem cell CD133AC133 antibody was prepared and evaluated by CD133 overexpression human glioblastoma cell T98G cell. The prepared liposomes had distribution on the cell surface but could not be taken into the inside of the cell due to low activity of CD133 internalization. Cancer stem cells are said to be difficult to image, but the possibility of antibody imaging was suggested.
