During development, the scleral ossicles are foreshadowed by a ring of papilliform thickenings in the conjunctival epithelium. The conjunctival papillae appear during the eighth day. They …

2018年12月8日 · The scleral cartilage is situated deeper within the sclera. In reptiles, it takes the form of a cartilage cup that lines the retinal pigmented epithelium externally (Fig. 2). The …

2006年2月22日 · Scleral papillae and scleral ossicles arise sequentially and in the same strict order. The first sign of ossification is present at day 11–12 (HH stage 37–38), preceded by a …

2018年4月1日 · The results of this study provide considerable insight into the spacing pattern of scleral papillae. A reaction-diffusion mechanism explains the ability of scleral papillae to …

2019年10月30日 · The papillae in the chicken embryonic eye, described as scleral papillae in the well-known Hamburger and Hamilton (1951) staging table, are one of the key anatomical …

We have used a polyclonal antibody against tenascin (a 240 kDa extracellular matrix glycoprotein) and indirect immunofluorescence to investigate the distribution of tenascin in cryostat sections …

The membrane bones or scleral ossicles (usually 14 in number) form an imbricated ring surrounding the corneal limbus. During development, the scleral ossicles are foreshadowed by …

Eyes of early embryonic chicks possess 14 scleral papillae, derived from the conjunctival epithelium and present as transient structures between seven and 11 days of incubation. …

2012年5月1日 · These papillae are small, transient clusters of epithelial cells that form outgrowths of the conjunctival epithelium (Coulombre and Coulombre, 1962). Despite the fact that these …

The papillae in the chicken embryonic eye, described as scleral papillae in the well‐known Hamburger and Hamilton (1951) staging table, are one of the key anatomical features used to …
