Overview
Stem cell therapy has emerged as a potential breakthrough treatment for degenerative retinal diseases, which are a leading cause of irreversible blindness. Unlike current therapies that aim to delay disease progression, stem cell therapy offers the possibility of regenerating damaged retinal tissue and restoring visual function.
The eye's unique characteristics, including its accessibility, immune-privileged status, and the availability of tools to monitor treatment outcomes, make it an attractive target for stem cell therapies. Researchers are exploring various sources of stem cells, such as embryonic stem cells, induced pluripotent stem cells (iPSCs), and adult stem cells, to develop treatments for retinal disorders.
Therapeutic Approaches
There are two main approaches to retinal stem cell therapy:
Cell Replacement Therapy
Differentiated stem cells are transplanted to replace damaged or lost retinal cells, such as retinal pigment epithelium (RPE) cells, photoreceptors, or ganglion cells.
Regenerative Therapy (paracrine effect)
Transplanted stem cells secrete trophic factors that stimulate resident retinal cells to proliferate and self-repair, mimicking the normal developmental process.
Indications and Clinical Trials
Several retinal diseases are being investigated as potential targets for stem cell therapy, including:
1. Age-related macular degeneration (AMD)
3. Myopic macular degeneration
4. Glaucoma
Clinical trials are underway to assess the safety and efficacy of stem cell therapies for these conditions. For example, transplantation of human embryonic stem cell-derived RPE cells is being studied in AMD, Stargardt disease, and myopic macular degeneration. Autologous bone marrow-derived stem cells are also being investigated as a potential treatment for glaucoma-associated ganglion cell loss.
