Research team Arne Östman

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.

Tumor microenvironment

Projects commonly integrate experimental studies and profiling of clinical samples. Studies have been performed across a broad range of tumor types, including breast, prostate, ovarian, colorectal and kidney cancer. A series of ongoing studies take advantage of novel methods for high content tissue profiling, which are used both for tumor biology discovery and identification of drug targets and biomarkers.

The group actively encourage studies that take advantage of the complementary expertise of biologists, pathologists and oncologists. The group also has a longstanding track-record of studies performed in collaborations with pharma companies and biotech start-up companies.
