The extracellular matrix and its cell surface receptors are thought to be important in development. Recent applications of targeted mutagenesis in mice have begun to test hypotheses based on in vitro data and patterns of expression. 'Knockout' mutations of matrix molecules and integrins reveal complexities arising from multiple receptors and ligands.
