1. Proteomics profiling or urinary EVs:- Diagnostic & prognostic testing
- Developed a clinical applicable urinary EV-capture method- Bijnsdorp et al, J Extracell Vesicles, 2017
- Large biobank: urine and blood sample collection- Current: validation of markerpanel
2. Biological role of prostate cancer EVs in metastasis:- Focus on preventing bone metastasis
- Mouse studies demonstrated that cancer EVsinfluence early metastasis:
formation and type of bone metastases

Tumor microenvironment and inflammation:Preclinical mouse models to define cancer EV-induced alterations of the tumor microenvironment
Using in vivo tumor models and next-generation techniques we aim to: • Globally define the immune profile alterations induced by cancer EVs • Evaluate the efficacy of specific combinations of immunomodulatory drugs to
block the pro-metastatic effects of cancer EVs • Identify circulating EV-associated biomarkers for treatment response prediction
We are currently looking for PhD candidates, visit www.exosomes.nl or www.werkenbijvumc.nl
