| Figure 1: Exosomes as carriers for therapeutic cancer-targeting drugs. An anticancer drug, for example, is designed to interact with CD81/Wnt11-exosomes in vivo (Route 1). The drug will kill cancer cells and cut off the signal transduction between stromal cells and cancer cells, so that no new exosomes are released by stromal cells (Route 2). Cancer cell migration and metastasis can thus be blocked. |
