Fibroblasts secrete and organize extracellular matrix (ECM), which provides structural support for their adhesion, migration, and tissue organization, besides regulating cellular functions such as growth and survival. Cell-to-matrix interactions are vital for vertebrate development. Disorders in these processes have been associated with fibrosis, developmental malformations, cancer, and other diseases. This unit describes a method for preparing a three-dimensional matrix derived from fibroblastic cells; the matrix is three-dimensional, cell and debris free, and attached to a two-dimensional culture surface. Cell adhesion and spreading are normal on these matrices. This matrix can also be compressed into a two-dimensional matrix and solubilized to study the matrix biochemically. © 2016 by John Wiley & Sons, Inc.
