Tumor Microenvironment. The research aims at a better understanding of the paracrine interplay in the tumor microenvironment between malignant cells, fibroblasts, vascular cells and immune cells. Particular attention is given to the roles of the PDGF system in this context. During the last years we have also identified other proteins, involved in this interplay, that affect tumor growth and metastasis.
Sarcoma Tumor Microenvironment. Cells of the tumor microenvironment control tumor growth, metastasis and response to treatment. These aspects of tumor biology are well studied in tumors derived from epithelial cells, but much less described in sarcomas. These malignant tumors of mesenchymal origin can be found almost anywhere in the body and include subtypes like rhabdomyosarcoma, Ewing sarcoma and osteosarcoma.
