Fig. 8. Effects of ephrin-B1-Fc on neural crest cell morphology. Cells were plated on coverslips coated with ephrin-B1-Fc (10 µg/ml) or fibronectin (10 µg/ml). After 4 hours, cells were fixed and immunolabelled with rhodamine-conjugated phalloidin and anti-vinculin antibody. The figure shows cells representative of each treatment.
