Stem cell therapy for retinal diseases
摘要
In this review, we discuss about current knowledgeabout stem cell （SC） therapy in the treatment of retinaldegeneration. Both human embryonic stem cell andinduced pluripotent stem cell has been growth inculture for a long time, and started to be explored inthe treatment of blinding conditions. The Food andDrug Administration, recently, has granted clinical trialsusing SC retinal therapy to treat complex disorders, asStargardt＇s dystrophy, and patients with geographicatrophy, providing good outcomes. This study＇sintent is to overview the critical regeneration of thesubretinal anatomy through retinal pigment epitheliumtransplantation, with the goal of reestablish importantpathways from the retina to the occipital cortex of thebrain, as well as the differentiation from pluripotentquiescent SC to adult retina, and its relationshipwith a primary retinal injury, different techniques oftransplantation, management of immune rejection andtumorigenicity, its potential application in improvingpatients＇ vision, and, finally, approaching future directionsand challenges for the treatment of several conditions.
