EVs derived from tumors undergoing treatment-induced immunogenic cell death seem particularly relevant in tumor immunosurveillance. This protocol exemplifies the assessment of oxaliplatin-induced immunostimulatory tumor EVs but can be adapted to various settings.

Medicine The Influence of Liver Resection on Intrahepatic Tumor Growth Hannes H. Brandt1, Valérie Nißler2, Roland S. Croner3 1Friedrich-Alexander-University Erlangen-Nürnberg (FAU), 2Department of Surgery, University Hospital Regensburg, 3Department of Surgery, University Hospital Erlangen A high incidence of tumor recurrence after resection of liver metastases remains an unsolved problem. The illustrated mouse model may be useful to investigate the reasons for such recurrences. It combines a liver resection model with intrahepatic tumor cell injection for the first time.
