概括

人体脂肪干细胞 (ASC) 在肢体干细胞缺乏症 (LSCD) 中显示出眼睛表面再生的前景. 虽然安全可行,但治疗效果因原因而异,并随着时间的推移而减弱.

科学领域:

眼科医生眼科眼科
再生医学是一种再生医学.
干细胞疗法干细胞疗法

背景情况:

双边四肢干细胞缺乏症 (LSCD) 损害了眼睛表面的完整性.
目前对LSCD的治疗有局限性.
自主脂肪组织衍生成人介质干细胞 (ASCs) 提供了潜在的治疗途径.

研究的目的:

评估使用自ASC用于双侧LSCD患者的眼表面再生的安全性和可行性.

主要方法:

一个IIa期临床试验,涉及8名患有不同原因的LSCD的患者.
手术方案包括角膜脱bridement,ASC注射到四肢象限,局部ASC悬浮,和胚胎膜移植.
长期随访 (平均86.5个月) 评估了安全性和有效性.

主要成果:

在随访期间没有报告任何不良事件.
在8名患者中,有6名患者在一年内成功移植,在5年内视力敏度得到改善.
到最后一次随访时,所有患者的上皮质缺陷都消失了,尽管疗效因病因而异,并随着时间的推移而减弱.

结论:

自生ASCs代表了双边LSCD的可行和保守的治疗方法.
ASCs的治疗疗效取决于LSCD的潜在原因,并且可能在长时间内下降.

iPS Cell Differentiation

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.
