In the avian embryo, the otic primordia become visible by Hamburger and Hamilton stage 10 as a pair of thickened regions of head ectoderm. In contrast to other epithelial primordia, invagination occurs by means of formation of a series of folds in di

The eye has fascinated scientists from the earliest days of biological in vestigation. The diversity of its parts and the precision of their interaction make it a favorite model system for a variety of developmental studies. The eye is a particular

The inner ear forms by a series of folds within an ectodermal placode. Previous work has shown that changes in surrounding tissues play a more prominent role in invagination than changes in the cytoskeleton of the primordium. Interference with the in

Immunolocalization of laminin, fibronectin, and type IV collagen was examined during early morphogenetic shape changes of the avian inner ear and eye. The ear was studied from formation of the otic placode to invagination of the otic pit and the eye

Differentiation of respiratory endings in the fetal lung appears to be controlled by its surrounding mesodermal capsule. The capsule may exert its influence by controlling the composition of the epithelial basal lamina or of the extended extracellula

The extensive changes in pulmonary function occurring during early development may reflect variations in the anatomic structure of the respiratory apparatus during this period. Accurate definition of these alterations could yield important informatio

The thyroid forms as an outpouching of the ventral pharynx. Evidence supports the conclusion that formation of the thyroid pit is mediated by changes in the cytoskeleton that cause constriction of cell apices. However, it seems unlikely that a relati
