H-RPE – Human Retinal Pigment Epithelial Cells

Catalog #: 00194987
H-RPE, Retinal Pigment Epithelial Cells
670.00 USD

Product Overview

The retinal pigment epithelium (RPE) consists of pigmented cells situated between the neuroretina and the choroids. The RPE is comprised of hexagonal cells organized into a monolayer that is densely packed with pigment granules. The RPE is of the neuroectodermal origin and is  therefore considered to be part of the retina. RPE cells play a critical role in visual function and photoreceptor viability.

Lonza's Human RPE cells are cryopreserved, primary RPE cells that are packaged at passage 2 and contain ≥500,000 cells per vial.  HRPE are guaranteed through 5 population doublings and stain positive (≥90%) for pancytokeratin and Zo-1 and negative (≤10%) for fibroblast contamination and endothelial marker CD31 ( ≤1%). They also test negative for mycoplasma, bacteria, yeast, and fungi. HIV-1, hepatitis B and hepatitis C are not detected for all donors and/or cell lots. A Certificate of Analysis (CoA) is provided for with cell lot purchased.

Structure of Retinal Epithelial Cells

The apical membrane of the RPE faces the photoreceptor’s outer segments and its basolateral membrane faces Bruch’s membrane. Bruch's membrane separates the RPE from the fenestrated endothelium of the choriocapillaris (Fig 2). The RPE constitutes the outer blood-retinal barrier (BRB). The inner BRB is mainly constituted by the endothelial cells. Tight junctions between neighboring RPE cells and neighboring endothelial cells are essential in the strict control of fluids and solutes that cross the BRB as well as in preventing the entrance of toxic molecules and plasma components into the retina.
