Transdifferentiation of chick embryonic retinal pigment epithelial cells to lentoid structure in suspension culture.
To test transdifferentiation of retinal pigment epithelial (RPE) cells in suspension culture, chick embryonic RPE sheets and dissociated RPE cells were cultured for two months in a non-adherent dish for suspension culture. RPE cells, isolated as a sheet, aggregated immediately and remained the same size with their differentiated characteristics for two months. The presence of basic fibroblast g...
متن کاملTissue culture of human retinal pigment epithelium.
Adult human retinal pigment epithelium has been enzymatically isolated and established In tissue culture. Primary cultures survived three to six months. Occasionally, cell lines spontaneously evolved from primary cultures. Melanin granules decreased with the age of the culture, became less pigmented but retained some characterstics of melanin-producing cells. Lipofuscin granules are present, bu...
متن کاملIdentification of GABA receptors in chick retinal pigment epithelium.
PURPOSE The retinal pigment epithelium (RPE) is a multifunctional, monolayer of cells located between the neural retina and the choroicapillaris. γ-Aminobutyric acid (GABA) is the most important inhibitory neurotransmitter in the retina and GABA receptors are known to be present in chick retina, sclera and cornea. There is a report of genes involved in GABA receptor signaling being expressed in...

www.expert-reviews.com ISSN 1746-9899 © 2011 Expert Reviews Ltd 10.1586/EOP.11.70 The retinal pigment epithelium (RPE) is a cellular monolayer between the neural retina and Bruch’s membrane. It adheres to and interacts with the underlying Bruch’s membrane at its basal side and with the photoreceptor outer segments at its apical side. It contributes to a turnover of photoreceptor outer segment, ...
متن کاملBone morphogenetic proteins specify the retinal pigment epithelium in the chick embryo.
In vertebrates, the neuroepithelium of the optic vesicle is initially multipotential, co-expressing a number of transcription factors that are involved in retinal pigment epithelium (RPE) and neural retina (NR) development. Subsequently, extrinsic signals emanating from the surrounding tissues induce the separation of the optic vesicle into three domains: the optic stalk/nerve, the NR and the R...
