| abstractText | RNA in situ hybridization on early chicken embryos revealed that the beta3 integrin gene started to be expressed after Hamburger and Hamilton (HH) stage 6 in the presumptive epidermis adjacent to the neural plate, before closure of the neural tube. The beta3 integrin gene was also strongly expressed in cephalic neural crest cells at the same stage in which they begin their migration but disappeared progressively in these cells along the route they take to the branchial arches. The gene was weakly expressed in the differentiating cranial neural crest cells. The alphaVbeta3 integrin protein complex was also mainly detected in the migratory cephalic neural crest cells. However, during early mouse embryogenesis and in contrast to the chick, the beta3 integrin gene was expressed in the foregut diverticulum and in the heart and not in the cephalic neural crest cells. Therefore, the difference in the beta3 integrin expression suggests that mouse and chicken cranial neural crest cells may have distinct integrin requirements during their ontogenesis.
