The mesodermal capsule of the fetal lung plays a role in differentiation of the respiratory region. It has been proposed for other epithelial organs that the mesodermal capsule influences development by modifying the basal lamina or the extended extr

Previous studies have shown that beta-xyloside inhibits maturation of the fetal mouse lung (Smith et al., Dev. Biol. 138, 42-52, 1990). Insofar as this drug inhibits proteoglycan deposition, the present studies were undertaken to examine the chemical

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

Experiments were done to investigate the cause of the cranial (mesencephalic) flexure of the chick brain during stages 10 to 14. Measurements of the length and thickness of the roof and floor of the mesencephalon gave values similar to the values obt

Mechanical properties of the proximal airways are known to change with development; the highly compliant airways of the immature animal become stiffer and less collapsible with increasing age. Although the relationship between tracheobronchial archit

Chick embryos, during stages 14 to 25, undergo an arching of the hindbrain and cervical neural tube that is termed cervical flexure. We have found that if the truncus arteriosus is severed during stage 12-13, the embryos survive for more than 24 h an

If a graft is placed in an early chick wing bud, the location of the graft after several days of further development cannot be predicted solely from the rate of proximal-distal outgrowth. The movement of the graft depends on the rate of outgrowth of

Cartilage cells are characterized by a high concentration of extracellular sulfated proteoglycan. Electron microscopic autoradiography was used to compare the incorporation of sulfate into proteoglycan by limb-bud chondrogenic and myogenic cells. Fro
