Figure 1. Characterization of injectable MPs loaded with FGF1 and NRG1.

Figure 1

(A) MP size distribution. (B) Scanning electron microscopy images showing the morphology of MPs. (C) Encapsulation efficiency. Western blot bands corresponding to FGF1/NRG1 standard curve and FGF1/NRG1 encapsulated in MPs (D) In vitro effect of MP-released cytokines on heart-derived cells. H9c2 cells were cultured in the presence of either MP-released or free FGF1 and NRG1. Values are the mean fold-increase in cell number over a 72-h period ± SEM from three independent experiments. (One–way ANOVA with a post-hoc Tukey’s multiple comparison test; **p < 0.01 ***p < 0.001).
