Induced Pluripotent Stem Cells (iPSC)

Overview

Introduction

Induced pluripotent stem cells enable patient-specific disease modelling by reprogramming adult cells into pluripotent stem cells. At Narayana Netralaya Foundation, iPSC research is used to study ocular diseases at a cellular level and connect genetic findings with functional outcomes.

Why This Research Matters

Many inherited retinal diseases progress silently before clinical symptoms appear. iPSC-derived retinal cells allow early disease mechanisms to be studied and therapies to be evaluated in human-relevant models.

Objectives

The iPSC programme aims to:

  • Generate patient-specific iPSC lines
  • Differentiate iPSCs into retinal cell types
  • Model disease progression in vitro
  • Support therapeutic testing and validation

Core Research Focus

The iPSC programme focuses on creating patient-specific cellular models to study disease mechanisms and evaluate therapeutic strategies in a controlled laboratory environment.

 

Core areas of focus include:

  • Generation of patient-derived iPSC lines from inherited ocular disease cases
  • Differentiation of iPSCs into retinal and ocular cell types, including RPE and photoreceptors
  • Modelling early-stage disease processes and cellular dysfunction
  • Studying genotype–phenotype relationships at a cellular level

A strong emphasis is placed on translational integration, including:

  • Functional validation of genetic variants identified through ocular genetics
  • Testing gene therapy and pharmacological interventions in human-derived cells
  • Correlating cellular phenotypes with clinical imaging and functional outcomes

Together, these efforts support a diverse portfolio of iPSC research, spanning various areas ocular and cellular dysfunction.

Team

The iPSC programme is led by a multidisciplinary team of scientists and clinician-researchers with expertise in:

  • Stem Cell Biology
  • Retinal Development
  • Molecular Genetics
  • Translational Ophthalmology

Close collaboration between laboratory researchers and clinicians ensures that research priorities remain aligned with patient needs and real-world clinical applicability.
