Trabecular Meshwork Regeneration for Glaucoma Treatment Using Stem Cell-Derived Trophic Factors

Area of Science:

• Ophthalmology
• Regenerative Medicine
• Cell Biology

Background:

• Glaucoma is a leading cause of irreversible blindness worldwide.
• Stem cell therapy shows potential for treating primary open-angle glaucoma in animal models.
• Stem cell-free therapy using trophic factors may benefit specific patient populations.

Purpose of the Study:

• To describe methods for trabecular meshwork stem cell (TMSC) cultivation and secretome harvesting.
• To outline protein isolation techniques from TMSC secretomes.
• To detail assays for assessing TMSC health and for periocular injection in mice.

Main Methods:

• Trabecular meshwork stem cell (TMSC) cultivation and expansion.
• Harvesting of TMSC-derived secretome and subsequent protein isolation.
• Assays for TMSC viability and functional assessment post-harvesting.
• Periocular injection of secretome in a mouse model for therapeutic evaluation.

Main Results:

• Established protocols for TMSC secretome production and protein isolation.
• Validated assays to ensure the quality and safety of the secretome.
• Demonstrated feasibility of periocular secretome delivery in a preclinical model.

Conclusions:

• The described methods provide a framework for developing stem cell-free therapies for glaucoma.
• Trabecular meshwork stem cell secretomes represent a promising therapeutic agent.
• This approach may offer an alternative for patients unable to undergo traditional stem cell therapy.
