Outline of Final Research Achievements |
The purpose of this study was to detect in vivo distribution of exosomes, which are an extracellular vesicle of about 100 nm diameter, secreted by cancer cells. The in vivo distribution of exosomes is expected to provide useful information to clarify the mechanism of promoting metastasis by cancer-derived exosomes. Because exosomes are about the same size as viruses, detection of delivery is difficult with current technologies. Therefore, in this study, we constructed an experimental system to detect delivery of exosomes derived from cancer cells by applying Cre-LoxP system. We developed technologies to increase the efficiency of the introduction of Cre recombinase into exosomes. However, we could not detect exosome delivery within this project.
