Interestingly, NanoSight quantitation revealed that HPSC cells secrete more sEVs (mean conc.4.75 × 10 10 particles/ml) compared to HPaStec cells (mean conc.1.35 × 10 10 particles/ml) from the equal number of cells seeded in an equal volume of CM which is marginally significant ( p = 0.0569) ( Table 1 ).
