Characterization of cancer-associated fibroblasts from ex vivo germ cell tumors

Cancer-associated fibroblasts (CAF) as one abundant cell type of the tumor microenvironment are known to have tumor supporting abilities by promoting tumor proliferation and modulating the immunal landscape. In this study, germ cell tumor-derived CAF were molecular and epigenetically characterized to identify CAF secreted signal molecules which play a pivotal role in the GCT-CAF interaction.
