Arne Östman's Group
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.

Projects commonly integrate analyses using cell- and animal-models of cancer together with correlative profiling of clinical samples. Studies have been performed across a broad range of tumor types, including breast, prostate, ovarian, colorectal and kidney cancer. Since some years a distinct program on the tumor microenvironment of sarcoma is being headed by Monika Ehnman.
The group actively promotes studies taking advantage of the complementary expertise of biologists, pathologists and oncologists. A number of projects have been performed in collaboration with pharma companies.
