Figure 3. MiRNAs profiles of exosomes derived from islets. Heatmap of the normalized expression levels of miRNAs differentially expressed in exosome of STZ (A) and cytokines (B) treated islets compared with control (x axis clustering showed different treatments). (C) Venn diagram show 6 differentially expressed miRNAs both in STZ and cytokines treated group compared with controls (shown in the overlap area).
