Fig. 1From: Stem cell-derived extracellular vesicles: role in oncogenic processes, bioengineering potential, and technical challengesA schematic overview of the role of extracellular vesicles (EVs) in the cellular microenvironment. EV cargo loads may contain a diverse set of molecules such as growth factors (VEGF, PDGF, FGF), inflammatory mediators (Alix, TNFα, TSG, IL-6, SDF-1), heat shock proteins (HSP90, HSP70), and microRNAs (mir-21, mir-178)Back to article page
