Abstract

Abstract Meibomian gland dysfunction (MGD) results in the increased tear film osmolarity and leads to the development of dry eye disease. Results obtained in several experimental and clinical studies suggested that mesenchymal stem cells (MSCs) could promote repair and regeneration of injured meibomian glands. We recently developed a new biological product “derived-Multiple Allogeneic Proteins Paracrine Signaling (d-MAPPS)” which activity was based on the effects of immunosuppressive and trophic factors secreted by MSCs. Herewith, we report a case of MGD treated by d-MAPPS containing eye drops, demonstrating therapeutic potential of d-MAPPS in regeneration of injured meibomian glands and in the attenuation of MGD. D-MAPPS containing eye drops significantly attenuated MGD-related symptoms (foreign body sensation, burning, pain in the eye and eye fatigue) and remarkably improved quality of life. The analysis of meibomian glands demonstrated restoration of meibomian gland morphology, structure and function, after the 3-weeks of d-MAPPS based therapy. MGD patient did not report any adverse effects related to the d- MAPPS administration, indicating that d-MAPPS containing eye drops were safe for intraocular application.
