Outline of Final Research Achievements |
Cancer stem cells are important subjects to understand the treatment resistance, latency and recurrence of cancer and to improve therapy. However, it was not easy to identify them in histological and cytological context. The mechanism how they give rise should be investigated with appropriate surface markers, which was not available. We have recently prepared a monoclonal antibody against ZnT1, a cancer stem cell surface marker candidate discovered by genetic analysis. Our specific aim was to visualize the developmental state of cancer stem cells by the use of the antibody. However, after careful investigations conducted under the present project, we concluded that the anti-ZnT1 antibody positive cell population was not identical to cancer stem cell populations identified by other methods. The expression status of this molecule did not correlate with the treatment resistance of cancer. However, we found that the developed monoclonal antibody is useful as a tool to analyze ZnT1.
