摘要:

背景:视网膜疾病以视网膜细胞损伤或凋亡为特点,缺乏理想的治疗方法。诱导多功能干细胞具有自我更新和多向分化潜能,不存在伦理道德问题,为干细胞移植治疗提供了新的来源,是当前研究的热点。
目的:综述诱导多功能干细胞在视网膜疾病治疗中应用的研究进展。
方法:第一作者应用计算机检索PubMed 相关文献,检索时间为2006年至2011年,检索词“induced pluripotent stem cells,retinal,photoreceptor,retinal pigment epithelium,retinal ganglion cell”并限定文献语言种类为English。共纳入42篇文章进行综述。
结果与结论:诱导多功能干细胞可以诱导分化为视网膜细胞,为细胞移植治疗提供来源,也可以作为疾病的模型来研究发病机制或者药物筛选,因此诱导多功能干细胞治疗视网膜疾病具有很大前景。然而,体细胞成功诱导为诱导多功能干细胞的效率低,并且存在致瘤的风险,有待更进一步研究。

Abstract:

BACKGROUND: Retinal diseases are caused by damage or apoptosis of the retinal cells and lack of ideal treatment. Induced pluripotent stem cells have self-renewal ability and differentiation potential. A new potential source from which to produce stem cells as a therapeutic platform for the treatment of retinal diseases and avoid ethics issues is the research focus currently.
OBJECTIVE: To review recent advancement of induced pluripotent stem cells and the potential utility for retinal diseases.
METHODS: The first author searched related articles published from 2006 to 2011 by computer retrieval in PubMed database using the keywords of “induced pluripotent stem cells, retinal, photoreceptor, retinal pigment epithelium, retinal ganglion cell” in English. Finally, totally 42 papers were involved.
RESULTS AND CONCLUSION: Induced pluripotent stem cells can be induced to differentiate into retinal cells which have a possibility to be used as donor cells for transplantation therapies. Patient-derived induced pluripotent stem cells can be used as disease models for mechanistic studies and drug screening. It is a promising therapy for retinal degenerative diseases. However, some problems still remain, such as risk of teratoma formation and low efficiency of somatic cells to be successfully induced into induced pluripotent stem cells. It still requires further more studies.
