科学领域:

神经科学是一个神经科学.
干细胞生物学干细胞生物学
遗传学是一个遗传学.

背景情况:

开发用于神经退行性疾病的有效治疗方法,如肌缩侧面硬化症 (ALS),由于缺乏相关的疾病模型,因此具有挑战性.
现有的动物模型往往无法完全回顾人类ALS的复杂性.

研究的目的:

创建一个强大的ALS体外模型,使用来自羊水膜的介质干细胞 (AM-MSCs).
在ALS研究中建立一个高效和具有成本效益的药物查平台.

主要方法:

AM-MSCs被分化为运动神经元 (MN),并与突变的人类SOD1 G93A等离子体转化,诱导一种类似于ALS的疾病.
鉴定包括基因表达分析,免疫细胞化学,流细胞测量,西斑和功能测试.
评估了运动神经元退化和模型效率.

主要成果:

分化AM-MSC表达了运动神经元标记物 (MNX1,Olig2,ChAT) 的升高.
SOD1 G93A的过度表达导致了下调的MN标记物,改变了基因表达 (NURR1上调),降低了乙胆和谷氨,并增加了氧化应激.
该模型展示了ALS病理学的特征.

结论:

一个新的体外ALS模型成功地使用AM-MSC衍生的运动神经元开发出来.
这种模型为研究ALS病变的动物模型提供了可行的替代方案.
该平台促进了对潜在的ALS治疗药物的高效和具有成本效益的药物查.

EPS and iPS Cells in Disease Research

Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...
