This includes the daily phagocytosis of shed Photoreceptor Outer Segments (POS), re-isomerization of all-trans-retinal to 11-cis-retinal in the visual cycle, protection against effects of photo-oxidation, trans-epithelial transport as well as the polarised secretion of molecules towards the overlying neuroretina and the underlying choroid. Occupying this strategic position in the outer retina the RPE performs multiple functions which are essential for retinal homeostasis and maintenance of life-long vision. The retinal pigment epithelium (RPE) consists of a monolayer of largely cuboidal-shaped pigmented cells found beneath the neuroretina and overlying the vascular blood supply of the choriocapillaris. As well as recapitulating salient structural and physiological features of native RPE, other advantages of this model include its simplicity, rapid set-up time and unlimited scope for detailed single-cell resolution and matrix studies. This in-vitro model therefore has the benefit of achieving the 3Rs objective of reducing and replacing the use of animals in research. The work presented here will enable users to rapidly establish a realistic in-vitro model of the outer retina that is amenable to a high degree of experimental manipulation which will also serve as an attractive alternative to using animals. We also discuss how RPE cells from human foetal and stem-cell derived sources can be incorporated alongside sophisticated BrM substitutes to replicate the aged/diseased outer retina in a dish.
These models can be used to study dynamic, intracellular and extracellular pathogenic changes using the latest developments in microscopy and imaging technology. We show that confluent monolayers of the spontaneously arisen human ARPE-19 cell-line cultured under optimal conditions reproduce key features of native RPE. In this article we describe the step-by-step approach required to establish an experimentally versatile in-vitro culture model of the outer retina incorporating the RPE monolayer and supportive Bruch’s membrane (BrM). In contrast, in-vitro models provide an attractive alternative to investigating pathogenic RPE changes associated with age and disease. Some studies are also difficult to carry out in animals as the ocular space remains largely inaccessible to powerful microscopes. Many studies into RPE pathobiology have utilised animal models, which only recapitulate limited disease features. However, the precise role of RPE cells in disease aetiology remains incompletely understood. Alterations to RPE structure and function are reported in Age-related Macular Degeneration, Stargardt and Best disease as well as pattern dystrophies.
