The unusual microtubule polarity in teleost retinal pigment epithelial cells. [PDF]

open access: yes, 1988
In cells of the teleost retinal pigment epithelium (RPE), melanin granules disperse into the RPE cells long apical projections in response to light onset, and aggregate toward the base of the RPE cell in response to dark onset.

Differentiating the Clinical and Variant Spectrum of Hardikar Syndrome From Other MED12‐Related Developmental Disorders

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The rare X‐linked female‐restricted Hardikar syndrome (HDKR, OMIM # 301068) is characterized by multiple congenital anomalies including orofacial clefts, gastrointestinal, genitourinary, and cardiac anomalies, but cognitive and neurobehavioral development is rarely impaired.

Single-channel recordings from cultured human retinal pigment epithelial cells. [PDF]

open access: yes, 1988
We have applied patch-clamp techniques to on-cell and excised-membrane patches from human retinal pigment epithelial cells in tissue culture. Single-channel currents from at least four ion channel types were observed: three or more potassium-selective ...

Transthyretin levels in the vitreous correlate with change in visual acuity after vitrectomy [PDF]

open access: yes, 2009
Background/aim: Little is known about biochemical markers related to change in visual acuity after vitrectomy. The potential use of transthyretin (TTR), a carrier of the retinol/retinol-binding protein, as a biochemical marker protein, was investigated ...

Induction of the retinal pigment epithelium of the chicken embryonic eye

open access: green, 1997
During 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.

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

open access: yesThe Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Loss of synchronized retinal phagocytosis and age-related blindness in mice lacking alphavbeta5 integrin. [PDF]

open access: yes, 2004
Daily phagocytosis by the retinal pigment epithelium (RPE) of spent photoreceptor outer segment fragments is critical for vision. In the retina, early morning circadian photoreceptor rod shedding precedes synchronized uptake of shed photoreceptor ...

Understanding the spacing of placodes in the eye: A comparative study across age and species

open access: yesThe Anatomical Record, EarlyView.
Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.
