Cell therapy in degenerative retinal diseases: expectations and threats Review article

Main Article Content

Anna Machalińska

Abstract

Currently, for many retinal degenerative diseases there is no effective treatment based on disease etiology. Neurotrophic factors secreted by the applied cells are responsible for improved morphology and function of degenerative retina. Moreover, these cells present immunomodulatory effect and reduce the inflammatory response of the damaged tissue. The best effect is obtained at the initial stage of the disease. Despite promising preliminary results, cell therapy requires further investigation to evaluate its efficacy and long-term safety. It is worth to underline that cell therapy should be conducted only as part of free clinical trials in certified research centers after obtaining the patient's informed consent for treatment.
