| Research Abstract |
Innovative therapeutics is required to improve prognosis of pediatric cancer. Several tumor suppressor microRNAs are identified and clinical application of microRNAs are suggested. Exosome plays important roles in intercellular communication of microRNA. We examined if exosome can be used to deliver tumor suppressor microRNA to pediatric cancer cells. It is revealed that pediatric cancer cells secrete exosome, that expression pattern of exosome-derived microRNA is similar to that of cellular microRNA and that exosome functions as menas of intercellular communication. Our findings suggested that exosome can be used as means of microRNA delivery.
