CAFs and the ECM | Webinar
January 26, 2026
Join this ECM Pharmacology Symposium to explore how cancer-associated fibroblasts (CAFs) and the extracellular matrix (ECM) operate as functional units that shape tumor biology — and how these mechanisms can be translated into clinically useful readouts. The session connects mechanistic insights from human pancreatic and breast cancer with emerging non-invasive ECM-derived biomarkers of CAF activity and immune cell dynamics.
Agenda
- Welcome and Introduction (Chair) | Dr. Morten Karsdal — 10 min
- CAF/ECM Functional Units and Clinical Translation in Human Pancreatic Cancer | Prof. Dr. Edna Cukierman (Fox Chase Cancer Center) — 20 min
- Copper Depletion, ECM/Collagen Remodeling, and Immune Response in Breast Cancer | Prof. Dr. Linda T. Vahdat (Dartmouth Hitchcock Medical Center) — 20 min
- Non-Invasive ECM-Derived Biomarkers of CAF and Immune Cell Activity in Clinical Cancer Research | Dr. Nicholas Willumsen (Nordic Bioscience) — 20 min
- Q&A — 20 min
Scientific topics
CAFs and the ECM do not act as background structure in tumors: they form interacting, measurable functional units that influence tissue mechanics, signaling, and immune context. In pancreatic cancer, these CAF/ECM units are central to how tumors organize their local environment, including ECM deposition and remodeling patterns that can affect therapeutic response and disease behavior, where immune regulation also plays a part of this unit-level biology.
In breast cancer, ECM remodeling, particularly collagen turnover and reorganization, links directly to immune activity and tumor progression. A clinically relevant question is which upstream levers shift ECM remodeling in ways that also alter immune response. This webinar includes insights into how copper depletion can influence collagen remodeling and immune dynamics, with implications for how ECM state may be modified and monitored in patients.
Finally, translation requires measurement. Non-invasive ECM-derived biomarkers offer a practical route to quantify CAF activity and immune cell-associated processes in clinical research. The session covers how circulating ECM fragments can be used as readouts of tumor microenvironment activity, supporting patient stratification, pharmacodynamic monitoring, and hypothesis testing in clinical trials.

Prof. Dr. Edna Cukierman
- Prof. Dr. Edna Cukierman is the Marvin & Concetta Greenberg Chair in Pancreatic Cancer Research and ACS Wilmott Family Professor of Pancreatic Cancer at Fox Chase Cancer Center.
- She is Co-Leader of the Cancer Signaling and Microenvironment Program and Director of the Spatial Immuno-Proteomic Initiative, specializing in high-plex spatial immunofluorescence.
- Her research centers on the desmoplastic tumor microenvironment (TME) and how cancer-associated fibroblasts (CAFs) and CAF-generated extracellular matrix (ECM) regulate tumor progression.
- Prof. Dr. Cukierman’s laboratory pioneered a unique 3D culture system that mimics in vivo mesenchymal stroma to study functional tumor–stroma interactions.
- She developed Harmonic Output of Stromal Traits (HOST) and the HOST-Factor, a quantitative framework to define functional states of TME cells.
- Her work dissects how CAF–ECM units interact with immune cells, nerves, and cancer cells to drive tumor-supportive or tumor-suppressive behaviors.
- A key focus is evaluating HOST-Factor values as TME-based prognostic biomarkers and predictors of therapeutic response.
- Prof. Dr. Cukierman integrates high-plex spatial immunofluorescence with AI-guided image analysis to generate cell-resolved TME functional maps.
