The transcription factor Ets-1 is expressed in many different migratory cell types, suggesting that it may play an important role in regulating motility. To determine whether its expression in the neural crest is consistent with such a function, we have performed a detailed analysis of its expression during early chick embryogenesis. Our results show that this transcription factor is up-regulated in the cranial neural folds and dorsal neural tube approximately 4-6 h prior to commencement of neural crest migration. c-Ets-1 continues to be expressed by migrating cranial neural crest cells and subsequently by some neural crest-derived tissues. In addition to neural crest, we find expression of c-Ets-1 in endothelial cells of blood vessels, in somitic and intermediate mesoderm, in limb buds and in the heart.
