Arne Östman is a Senior Professor at the Department of Oncology-Pathology, Karolinska Institutet , specializing in tumor microenvironment research. His work bridges pre-clinical studies and clinical applications, focusing on cancer-associated fibroblasts (CAFs), PDGF signaling, and biomarker development for drug targeting. Key Research Themes: Tumor-stromal interactions CAFs in breast, prostate, ovarian, colorectal, and kidney cancers Novel spatial tissue profiling methods Drug target identification in stromal cells Recent Articles highlight PDGF system roles, FAP+ fibroblasts, and NRF2 in metastasis across multiple tumors. Collaborations include SciLifeLab , clinical researchers, and pharmaceutical partners. Scientific Contributions include grants from the Swedish Cancer Society (80 million SEK) and Radiumhemmet (33 million SEK) for tumor microenvironment studies. His team has identified CAF subtypes and stromal-immune crosstalk mechanisms with clinical utility.
