The extracellular matrix (ECM) is a complex network of proteins and other molecules that provide structural support and regulation for cells in tissues and organs. It plays a crucial role in many biological processes, including cell adhesion, migration, signaling, and differentiation. Research in this area focuses on understanding the composition and function of the ECM, as well as how changes in the ECM can contribute to various diseases, such as cancer, fibrosis, and tissue degeneration. Scientists are also exploring potential therapeutic strategies that target the ECM to treat these conditions.
