Isolation and characterization of exosome from human embryonic stem cell-derived c-myc-immortalized mesenchymal stem cells
2016
Mesenchymal stem cells (MSC) are currently the cell type of choice in many cell therapy trials. The number of therapeutic applications for MSCs registered as product IND submissions with the FDA and initiation of registered clinical trials has increased substantially in recent years, in particular between 2006 and 2012. However, defined mechanisms of action underpinning the therapeutic efficacy of MSCs are lacking, but they are increasingly attributed to MSC trophic secretion rather than their differentiation potential. A promising secreted therapeutic candidate is an extracellular vesicle (EV) known as the exosome. The use of exosomes instead of cells as a therapeutic agent provides several advantages. A critical advantage is the prospect of a conventional pharmaceutical manufacturing process that is highly scalable and amenable to the stringent manufacturing process. For example, MSCs used as producers of therapeutics, and not as therapeutics per se, could be immortalized to generate infinitely expansible clonal lines to enhance the reproducible production of therapeutic exosomes. In this chapter, we will describe the immortalization of MSCs, and the production, isolation, and characterization of exosomes from immortalized MSC.
