Fibronectin in the developing sea urchin embryo.
The presence of fibronectin in developing sea urchin embryos was studied uing immunofluorescence staining. The fluorescence pattern indicates that fibronectin is found on the cell surfaces and between cells in the blastula and gastrula stages, indicating that it plays a role in cell adhesion. Its presence on invaginating cells also suggests its involvement in morphogenesis during early development.
