Collagen organization in the secondary chick cornea during development.
PURPOSE The latter stages of morphogenesis in the embryonic chick cornea are instrumental in the establishment of a properly formed corneal stroma. This study was designed to provide better appreciation of collagen reorganization in the avian corneal stroma during the latter stages of embryogenesis. METHODS High-angle synchrotron x-ray diffraction patterns were obtained from 47 developing chi...
متن کاملBiosynthesis of Collagen and Non-collagen Protein during Development of the Chick Cornea
The relationship between the rates of increase of corneal protein fractions and incorporation of labeled precursors has been examined during embryonic and early posthatching development of the chick corneal stroma. Non-collagen protein increased gradually from 9 through 20 days of incubation. Collagen accumulated approximately logarithmically through the 19th day, the most rapid rate occurring ...
متن کاملFibroblast-collagen interactions in the formation of the secondary stroma of the chick cornea
Fibroblasts invade the primary corneal stroma of the 6-day-old chick embryo eye. The way in which these cells build the secondary stroma has been studied by microscope examination of the stroma during the subsequent 8 Days. Eyes were embedded in low viscosity nitrocellulose, and 30-micrometer tangential sections of cornea were cut and stained with azan (giving blue collagen and red cells). Thes...
متن کاملCollagen Orientation During Development of the Embryonic Avian Cornea
Purpose: During the latter stages of development, the secondary chick corneal stroma undergoes significant structural and compositional changes. The current study was designed to provide information about the orientation of collagen molecules (and thus fibrils) as the cornea matures before hatching. Collagen orientation is an important biomechanical parameter given that collagen lamallae consis...
متن کاملAn immunofluorescent study of cornea development in the chick.
The developmental pattern of appearance of a structural corneal antigenic determinant was studied by immunofluorescent methods. It was first detected in the primary corneal stroma at stage 23, and thereafter spread throughout the primary and secondary stroma. This antigen was absent from Bowman's membrane at its initial stage of development, suggesting that this membrane is a new structure in c...
