1. This is similar to the embryonic apical ectodermal ridge, which forms during normal limb development.
2. However it has long been noted that zone of polarizing activity ( ZPA ) requires maintenance of apical ectodermal ridge ( AER ).
3. Abnormality of an embryonic structure called the apical ectodermal ridge, which helps direct early limb development, may also be involved in this disorder.
4. The "'progress zone "'is a layer of mesodermal cells immediately beneath the apical ectodermal ridge in the developing limb bud.
5. Other possible causes are an injury to the apical ectodermal ridge during upper limb development, intrauterine compression, or maternal drug use ( thalidomide ).
6. It's difficult to find apical ectodermal ridge in a sentence. 用apical ectodermal ridge造句挺難的
7. Emx1 is not only limited to the telencephalon, rather it is also expressed in branchial patterns and in the apical ectodermal ridge of the developing limbs.
8. Formation of human hands and feet begins at about the 6th week of gestation, when cell death divides the apical ectodermal ridge into, normally, five segments.
9. Epithelial-mesenchymal interactions between the apical ectodermal ridge ( AER ) and the underlying mesenchyme, denoted the progress zone, are required for normal morphogenesis of the limb.
10. The lateral plate mesodermal cells secrete a fibroblast growth factor ( FGF7 and FGF10, presumably ) to induce the overlying ectoderm to form an important organizing structure called the apical ectodermal ridge ( AER ).
11. This study is also cited in the demonstration that the growth and patterning of the underlying mesenchyme is highly dependent on the apical ectodermal ridge of the limbs, as well as the maxillary and mandibular branchial ectoderm that are so prominently disturbed in these mice.
12. The "'apical ectodermal ridge "'( "'AER "') is a structure that forms from the ectodermal cells at the distal end of each limb bud and acts as a major signaling center to ensure proper development of a limb.
13. The "'limb bud "'remains active throughout much of limb development, and its signaling stimulates formation of another signaling center, the apical ectodermal ridge ( AER ) as well as formation of the zone of polarizing activity ( ZPA ) within the mesenchyme.
