| Outline of Final Research Achievements |
Two microarray analyses found candidate genes, OLR1 and EBI3, which expressed commonly among 5 squamous cell carcinoma cells (HSC2, HSC3, HSC4, Sa3, and H1), showing high expression on the cell membrane. There are those gene clones in the cDNA library, which established by our previous another study, and the clones were able to be available in the present experiment. The high expression of these genes in oral cancer cells were confirmed by qRT-PCR. The efficiency to induct the expression vector to fibroblast and/or dendritic cells was evaluated and the efficiency to produce the exosomes was also evaluated. Exosomes were successfully extracted from human fetal fibroblast cells and the specific adsorption ability to cancer cells of exosomes was confirmed.
