Analyses and Utilization of Selectively Tuned Human Adipose-Derived Stromal/Stem Cell Exosomes

Methods Mol Biol. 2024:2783:309-322. doi: 10.1007/978-1-0716-3762-3_22.

Abstract

We have developed a hollow fiber bioreactor-based production system for manufacturing large quantities of extracellular vesicles (EVs) containing exosomes from adult human adipose-derived stromal/stem cells (ASCs). By manipulating the cellular bioreactor environment, we have found that we can alter ASC EV production, secretion, and surface protein composition. The aims of this chapter are to describe the methodology for culturing and tuning of adipose ASCs in a bioreactor, along with the collection and isolation of the EVs containing exosomes demonstrating increased HSP70 content.
