NCIt definition : The extracellular matrix is a network of fibers that hold cells together. It is found
within the extracellular space and in association with the basement membrane of the
cell surface. It promotes cellular proliferation and provides a supporting structure
to which cells or cell lysates in culture dishes adhere. It is broken down during
normal physiological and disease processes such as bone remodeling, embryogenesis,
cancer, and arthritis.;
