Controllable gelation of artificial extracellular matrix for altering mass transport and improving cancer therapies

Nature Communications, 2020
The extracellular matrix (ECM) can influence tumor growth and its response to therapy. Here, the authors develop a fibrinogen and thrombin based artificial ECM that can starve tumours and prevent dissemination of cancer cells.
