Abstract
Cell adhesion to extracellular matrices, including fibronectin, results in clustering of integrins in focal adhesions. To promote the clustering of fibronectin and thus enhance its activity at the sites of focal adhesion formation, we have engineered a fusion protein containing recombinant fibronectin fragment (hFN) connected to the tetramerization helix domain of lac repressor for oligomeric assembly. Purified Lac-hFN fusion protein exhibited significant increase of cell adhesion and proliferation of GF cells compared with hFN alone (p < 0.05).
