干细胞移植治疗视网膜神经节细胞损伤性疾病的研究进展

视网膜神经节细胞是视觉形成的重要参与者。视网膜神经节细胞损伤或死亡往往会导致视功能不可逆转的损害。青光眼、糖尿病视网膜病变、高血压、视网膜变性等致盲性疾病，均会引起视网膜神经节细胞损伤或进行性大量凋亡。目前此类疾病在临床上尚无明确的治疗方法。为了恢复患者视网膜神经节细胞功能，国内外学者将研究焦点集中在干细胞移植上。干细胞移植主要指两大类，一类是基于干细胞的替代治疗，另一类则是通过干细胞移植促进某些因子分泌来保护视网膜神经节细胞。我们旨在对干细胞移植治疗视网膜神经节细胞损伤疾病的潜力进行综述，并着重讨论不同种干细胞分化为视网膜神经节细胞的研究进展。

Progress in stem cell transplantation for treatment of retinal ganglion cell damage diseases

Retinal ganglion cells are crucial in the formation of vision. Injury or death of retinal ganglion cells may lead to irreversibly damage of visual function. Glaucoma, diabetic retinopathy, hypertension, and other blind leading diseases can cause the damage or progressively apoptosis of retinal ganglion cells. Currently, there is no specific treatment to restore vision damage caused by those diseases. Scholars at home and abroad focus on stem cells transplantation in order to recover the visual function of patients. Two categories are mainly involved in stem cell transplantation, one is the replacement therapy based on stem cells, the other is to promote the secretion of some factors to protect ganglion cells through stem cell transplantation. In this review, we aim to summarize the potential of stems cell transplantation to treat retinal ganglion cells related diseases, and discuss the differentiation of different types of stem cells to retinal ganglion cells.
