The pigmented layer of retina or retinal pigment epithelium (RPE) is the pigmented cell layer just outside the neurosensory retina that nourishes retinal visual cells, and is firmly attached to the underlying choroid and overlying retinal visual cells.

Retinal pigment epithelium (RPE) is formed from a single layer of regular polygonal cells arranged at the outermost layer of the retina. The outer side of the RPE is connected to Bruch’s membrane and the choroid, while the inner side is connected to the outer segment of photoreceptor cells.

Retinal pigment epithelial cells (RPE) constitute a simple layer of cuboidal cells that are strategically situated behind the photoreceptor (PR) cells. The inconspicuousness of this monolayer contrasts sharply with its importance [1].

视网膜色素上皮(rpe)是由排列在视网膜最外层的一层规则的多边形细胞组成。rpe的外侧连接布鲁赫膜和脉络膜，内侧连接光感受器细胞的外节。外侧呈现出基底内折叠样，这增加了细胞表面积，促进物质交换。位于布鲁赫膜最内层的半桥粒与基底膜紧密相连。

2024年11月1日 · The retinal pigment epithelium (RPE) between retinal photoreceptors and choroidal capillaries is a single layer of cells that are of critical importance to the eye. RPE cells are derived from the anterior neural plate of neuroectodermal origin.

视网膜色素上皮 [1] （retinal pigment epithelium，RPE）又称视网膜色素层（pigmented layer of retina），是一层紧贴于视网膜感觉神经之外的色素细胞，并影響视网膜视觉细胞。它与其下的脉络膜和其上视网膜神经细胞紧密相连。 [2] [3]

The retinal pigment epithelium (RPE), a monolayer of post-mitotic polarized epithelial cells, strategically situated between the photoreceptors and the choroid, is the primary caretaker of photoreceptor health and function. Dysfunction of the RPE underlies many inherited and acquired diseases that c …

2020年9月1日 · From a developmental perspective, the RPE is a neuroepithelium, derived from the outer layer of the optic cup. Functionally, the RPE acts as a secretory epithelium, a regulatory barrier, a professional phagocyte, and an antigen-presenting cell.

2016年7月11日 · The retinal pigment epithelium (RPE) occupies a functionally critical location in the human eye, sandwiched between the neural retina (NR) and the choroid. At first glance, the RPE appears strikingly simple and homogeneous in histological organization, presenting as a simple epithelial monolayer of pigmented, hexagonally packed cuboidal cells.

The retinal pigment epithelium (RPE) is a single monolayer of cells that resides between the light-sensitive photoreceptors and the fenestrated choriocapillaris. It performs specific functions in support of the photoreceptor cells, including the reisomerization of visual chromophore, and phagocytosis of photoreceptor outer segment (POS ...
