Figure 6. Potential mechanism of apoptosis activation in exosome-treated A2780 cancer cells.

Figure 6

(a) Exosome-treated cells displayed upregulated expression of pro-apoptotic molecules and downregulated expression of anti-apoptotic BCL2. (b) hAMSC-CM-derived exosome inhibition of A2780 cell proliferation. hAMSCs release exosomes in CM, where exosomes function as carriers of MSC-secreted miRNAs. Upon internalization by cancer cells, miRNA is released by exosomes to target genes expressing different molecules associated with cancer proliferation, thereby disrupting cancer metastasis. The experiments were repeated at least three times.
