Cell behaviour during optic vesicle morphogenesis in medaka
… starts with the bilateral evagination of optic vesicles from the forebrain. A failure of evagination leads to the complete absence of eyes. Despite a good knowledge about patterning and retina differentiation, the mechanism underlying evagination remained largely unknown. Studies on optic …

Induction of the retinal pigment epithelium of the chicken embryonic eye
… development of the eye, invagination of the optic cup gives rise to a double layered neuroepithelium, part of which differentiates into the retinal pigment epithelium (RPE). The molecular mechanisms which control differentiation of the RPE are not known. The present study was undertaken to …

Einfluss frühembryonaler Manipulation der Augenanlage auf das Verhalten und auf Positionsmarker im optischen Tektum des Haushuhns
… in the visual system of the chick we rotated one optic vesicle in embryos. The functionality of axonal connections was tested after hatching by examination of pecking behaviour, reflexes and the optokinetic nystagmus (OKN). The animal exhibited normal reflexes with both eyes, showing the …

Effects of benzo[a]pyrene and CYP19a1b knockdown on zebrafish development
… and CYP19a1b knockdown including body length, optic vesicle size, swim bladder inflation, pericardial and abdominal edema, and incidence of normal larval tail shape and these effects were reversed by exogenous E2-cotreatment. Decreased incidence of normal pectoral fins was only impacted by BaP …

Role of Xenopus Pitx3 during early development.
… suggest that xPitx3 directs development of the optic placode, and that without its influence; both the lens and retina fail to form. xPitx3 over-expression expands the early expression domains of Pax6 and Six3 and alters development of the lens, optic vesicle, optic nerve, and diencephalon. …

Characterisation of neural progenitors from the adult retina and ciliary epithelium
… presumptive neural retina of the invaginating optic vesicle. The Chx10 gene is expressed in the proliferating retinal progenitor cell population throughout retinal development hence is one of the earliest characterised RPC-specific markers. Mutations in the Chx10 homeobox gene cause reduced …
