• Effect of fibronectin on cultured cells derived from isolated micromeres of sea urchin embryos was examined. Fibronectin isolated from the sea urchin ovary (sea urchin fibronectin) accelerated the scattering of micromere-derived cells at the low concentration (0.01-0. 1 mg/ml). The acceleration of the scattering of cultured cells also occurred on the fibronectin-coated surface. However, at higher concentrations in a range of 0.2-0.8 mg/ml, sea urchin fibronectin enhanced the cellto-cell and cell-to-substratum adhesion of micromere-derived cells. Sea urchin fibronectin also induced the formation of spicules in the serum-deficient culture medium. Similar results were obtained with the application of horse or calf plasma fibronectin but to a lesser extent. The present study suggests that fibronectin may have an important role in migration, adhesion and spicule formation of cultured cells derived from isolated micromeres in vitro.
