Retinal disease modeling & safety assessment

Dry age-related macular degeneration (AMD)

Dry AMD model using iPSC-derived RPE cells exposed to chronic low-dose N-retinylidene-N-retinylethanolamine (A2E) and blue light to simulate lipofuscin photoactivation. The model recapitulates key features of dry AMD pathology, including RPE atrophy, oxidative stress, complement activation, and inflammatory signaling.

Comprehensive high content screening services for assessment of RPE health and function, including growth factor secretion (VEGF, PEDF), barrier integrity (TEER), phagocytosis, pigmentation and maturity markers, oxidative stress, complement activation, cell viability and apoptosis.

Automated 384‑well dry AMD screening platform enabling robust and reproducible screening of 6,000 compounds per run for preclinical drug discovery.

RPE-microglia co-culture model

iPSC-derived RPE cells and iPSC-derived microglia co-culture for modeling retinal inflammation and the impact of AMD-related stressors. RPE cells displayed increased sensitivity to A2E- and blue light–induced stress when co-cultured with microglia compared to monoculture conditions including microglial proliferation and elevated secretion of inflammatory cytokines.

Retinal organoids for discovery and retinal toxicity

Compound efficacy and toxicity testing using human iPSC‑derived retinal organoids, enabling assessment of therapeutic response, mechanism of action. Optimised retinal organoid-based screening systems for retinal toxicity with cell viability (ATP-based assays), morphological assessment, and short- and long-term treatment regimes.

Retinal organoids

iPSC-derived retinal organoids contain the major retinal cell types organized in a laminar structure, as shown by the expression of Recoverin (photoreceptors), Rhodopsin (rods), Opsin LW/MW and SW (cones), PKC-α (bipolar cells), AP-2α (amacrine cells), SNCG (ganglion cells), CRALBP (Müller glial cells), and PROX1 (horizontal cells).

Specialist services 

Services include reprogramming from patient cohort material and gene-editing. Custom differentiation of our iPSC lines, or client lines for retinal and ophthalmic research models, including retinal organoid generation. Preclinical drug discovery services, assay development, target validation, mode of action and safety.
