Adipose-derived mesenchymal stromal cells: A study on safety and efficacy in ocular inflammation
Purpose
This study explores the application of adipose-derived mesenchymal stromal cells (adMSCs) as a therapy for ocular inflammatory diseases utilizing a chronic GVHD model.
Methods
Human adMSCs were administered via subconjunctival injection into mice with chronic ocular GVHD. Clinical scores and changes in T cell populations were analyzed.
Results
The study showed significant improvement in corneal integrity, including epithelial damage, opacity, thickness, and structure, after subconjunctival adMSC transplantation. Additionally, adMSC transplantation increased CD45+ and Foxp3+ Tregs while decreasing CD4+ T cells, 1IL17A+ Th17 cells, and IFNγ+ Th1 cells in local cervical lymph nodes. Moreover, adMSC-conditioned media enhanced wound closure and cell migration toward the wound bed in vitro. The cells disappeared within a week suggesting that trophic factors were involved.
Conclusion
The dual benefit of adMSCs in immune-related ocular disorders underscores their potential for clinical application. This study focuses on subconjunctival delivery, effects of adMSCs and migration post-injection, with implications for optimizing cellular therapy application. The observed dual action, combining immunomodulation and tissue repair enhancement, underscores holistic approach of adMSC therapy in regenerative medicine, making it a potent treatment for diseases involving inflammation and tissue damage in the ocular surface.
期刊介绍：
The Ocular Surface, a quarterly, a peer-reviewed journal, is an authoritative resource that integrates and interprets major findings in diverse fields related to the ocular surface, including ophthalmology, optometry, genetics, molecular biology, pharmacology, immunology, infectious disease, and epidemiology. Its critical review articles cover the most current knowledge on medical and surgical management of ocular surface pathology, new understandings of ocular surface physiology, the meaning of recent discoveries on how the ocular surface responds to injury and disease, and updates on drug and device development. The journal also publishes select original research reports and articles describing cutting-edge techniques and technology in the field.
