Fig. 4From: Progress on pivotal role and application of exosome in lung cancer carcinogenesis, diagnosis, therapy and prognosisExosome isolation, characterization, and tumor-derived exosomes role in tumor development. Methods for exosome isolation and characterization are listed. Tumor-derived exosomes role in tumor development includes to promote cancer carcinogenesis, angiogenesis, and drug resistance, help cancer cell escape from host immune system, and can be useful diagnostic and/or prognostic biomarkers.Back to article page
