Tissue culture studies of the embryonal chicken retina.
نویسندگان
چکیده
Pure neuroectodermal growth was obtained from the retina of the chicken embryo by removing the pecten before preparation of the cultures. Retinal tissue was cultured either as explants in plasma clots or as isolated cells after trypsinization. Epithelial cells formed sheets on which the other retinal cells grew. Horizontal cells maintained the associational characteristics. Development of photoreceptors with incomplete outer segments was observed.

Dehydroepiandroesteron increased proliferation of neural progenitor cells derived from p19 embryonal carcinoma stem cells.
Introduction: The p19 line of embryonal carcinoma cells develops into neurons, astroglia and fibroblasts after aggregation and exposure to retinoic acid (RA). Dehydroepiandroesteron (DHEA) is a neurosteroid, can increase proliferation of human neural stem cell (NSC) and positively regulated the number of neurons produced. This study was initiated to assess the effect of DHEA on neural progenito...
متن کاملAmplification of DNA sequences during chicken cartilage and neural retina differentiation.
[3H]BrdUrd-substituted DNA probes were prepared from organ cultures of differentiating chicken neural retina and cell cultures of stage 24 chicken limb buds. Reassociation reactions using the neural retina probe demonstrated amplification of DNA sequences during differentiation of neural retina. This probe also contained sequences present in greater numbers in heart DNA than in DNA from undiffe...
متن کاملIn vivo volumetric imaging of chicken retina with ultrahigh-resolution spectral domain optical coherence tomography
The chicken retina is an established animal model for myopia and light-associated growth studies. It has a unique morphology: it is afoveate and avascular; oxygen and nutrition to the inner retina is delivered by a vascular tissue (pecten) that protrudes into the vitreous. Here we present, to the best of our knowledge, the first in vivo, volumetric high-resolution images of the chicken retina. ...
متن کاملA re-examination of lens induction in chicken embryos: in vitro studies of early tissue interactions.
Early studies on lens induction suggested that the optic vesicle, the precursor of the retina, was the primary inducer of the lens; however, more recent experiments with amphibians establish an important role for earlier inductive interactions between anterior neural plate and adjacent presumptive lens ectoderm in lens formation. We report here experiments assessing key inductive interactions i...
متن کاملP-88: Comparing Epigenetic Profile of Oct4 Regulatory Region in Embryonal Carcinoma Cells under Retinoic Acid Induction
Background: Embryonal carcinoma (EC) cells derived from germ cell tumors are valuable tools for investigating differentiation and developmental biology processes in vitro. The advantage of the reproducible and rapid expansion of these cell lines provides a useful alternative to embryos for the study of mammalian cell differentiation. During early stages of cell differentiation, the rate of tran...
