Heparin Can Augment Extracellular Vesicle Yield by Inhibiting Reuptake in Donor Cells During Cell Propagation [PDF]

open access: yesJournal of Extracellular Vesicles
Extracellular vesicles (EVs) mediate cell‐to‐cell communication in development, health and disease. Heparin is a common component in human induced pluripotent stem cell (hiPSC) media but its impact on hiPSC‐EVs beyond stabilizing growth factors is ...
