Moduli in the low and high stretch regions for fibrin strands are not increased after 30 days of EV-containing treatment groups. (A) Schematic of the mechanical testing procedure for fibrin strands and the definition of low and high stretch regions. (B) Modulus of the system in the low stretch region following culture with the treatments described in Figure 2. (C) Modulus of the system in the high stretch region following culture with the same treatments. No significant differences were detected using one-way ANOVA.
