In this review, we overview the pathophysiology of primary open-angle glaucoma as it relates to the trabecular meshwork (TM), exploring modes of TM dysfunction and regeneration via stem cell therapies.
Stem cells from a variety of sources, including trabecular meshwork, mesenchymal, adipose and induced pluripotent stem cells, have shown the potential to differentiate into TM cells or and to regenerate the TM , lowering intraocular pressure (IOP) and reducing glaucomatous retinal ganglion cell damage.
Stem cell therapies for TM regeneration provide a robust and promising suite of treatments for eventual lowering of IOP and prevention of glaucomatous vision loss in humans in the future. Further investigation into stem cell homing mechanisms and the safety of introducing these cells into human anterior chamber, for instance, are required before clinical applications in treating glaucoma patients.
在本综述中,我们概述了与小梁网(TM)相关的原发性开角型青光眼的病理生理学,探讨小梁网功能障碍的模式以及通过干细胞疗法实现小梁网再生的方式。
来自多种来源的干细胞,包括小梁网干细胞、间充质干细胞、脂肪干细胞和诱导多能干细胞,已显示出分化为小梁网细胞以及使小梁网再生的潜力,可降低眼压(IOP)并减少青光眼性视网膜神经节细胞损伤。
用于小梁网再生的干细胞疗法为未来最终降低眼压和预防人类青光眼性视力丧失提供了一系列强有力且有前景的治疗方法。例如,在将这些细胞应用于青光眼患者的临床治疗之前,还需要进一步研究干细胞归巢机制以及将这些细胞引入人眼前房的安全性。
