Exosomes are significant players in cancer progression. They facilitate numerous processes that aid in tumor growth and metastasis. Cancer cells release a higher quantity of exosomes compared to normal cells. These exosomes carry oncogenic proteins, miRNAs, and DNA that can transform neighboring normal cells into cancerous cells. They also promote angiogenesis by transporting pro-angiogenic factors, support the formation of a pre-metastatic niche, and suppress the immune response by delivering immunosuppressive molecules to immune cells.
