Exosome in Tumour Microenvironment: Overview of the Crosstalk between Normal and Cancer Cells

Figure 2

Major groups of exosomes based therapies, which include the removal of cancer derived exosomes, containing bioactive molecules, from the blood (or other body fluids) of cancer patients through a haemodialysis-like process; activation of the immune system against cancer cells by the use of vaccines of exosomes containing proteins with higher expression in tumour cell membranes; and use of exosomes containing microRNA (miRNA), small interference RNA (siRNA), and/or anticancer drugs for targeting delivery to cancer cells.
