ABSTRACT
Key roles for fibronectin and its integrin receptors have been postulated in the multiple cell-matrix interactions essential for chick embryo morphogenesis. However, mechanistic studies of these processes have been hampered by the current absence of sequence data and chicken cDNA clones for the major fibronectin receptor subunit, integrin α5 (ITGA5). We report here the sequence, endogenous expression pattern, and transfection of full-length chicken integrin α5. During early chicken embryonic development, α5 is highly expressed in cranial neural folds and migrating neural crest cells, suggesting potential roles in neural crest formation and migration. In fact, over-expression of this integrin in early neural tube selectively induces BMP5, a growth factor recently implicated in neural crest formation. Availability of these α5 integrin tools should facilitate studies of its functions in early embryonic development.
