人多能干细胞(HPSC)已经分化为星形胶质细胞,但hPSC来源的星形胶质细胞用于神经系统疾病的细胞治疗还没有得到很好的研究。星形胶质细胞是异质性的,并不是所有的星形胶质细胞在促进神经修复方面都是等同的。细胞治疗的一个先决条件是获得具有优越治疗效果的特定细胞群。在这里,我们使用一个Orig2-GFP人胚胎干细胞(HESC)报告来证明hESC来源的Olob2+祖细胞产生一种以前未描述的星形胶质细胞亚型(Opol2PC-Astros)。这些寡核苷酸星形胶质细胞与从寡核苷酸阴性hESC来源的神经前体细胞分化而来的星形胶质细胞(NPC-Astros)有很大的不同,特别是在神经保护特性上。当被移植到患有全脑缺血的大脑中时,与NPC-Astros相比,Opol2PC-Astros显示出更好的神经保护效果和改善的行为结果。因此,这种人脑星形胶质细胞分化的新模式对于研究人脑星形胶质细胞的异质性是有用的,而独特的寡核苷酸-Astros可能构成治疗脑缺血和其他神经系统疾病的一种新的细胞疗法。星形胶质细胞在表型上是不同的,并且并不是所有的星形胶质细胞在修复脑损伤方面的能力是相同的。在这里,作者展示了两种明确的星形胶质细胞亚型,它们来自hESC来源的寡核苷酸阳性神经前体细胞和寡核苷酸阴性神经前体细胞,显示出不同的特性和神经保护作用。
Human pluripotent stem cells (hPSCs) have been differentiated to astroglia, but the utilization of hPSC-derived astroglia as cell therapy for neurological diseases has not been well studied. Astroglia are heterogeneous, and not all astroglia are equivalent in promoting neural repair. A prerequisite for cell therapy is to derive defined cell populations with superior therapeutic effects. Here we use an Olig2-GFP human embryonic stem cell (hESC) reporter to demonstrate that hESC-derived Olig2+ progenitors generate a subtype of previously uncharacterized astroglia (Olig2PC-Astros). These Olig2PC-Astros differ substantially from astroglia differentiated from Olig2-negative hESC-derived neural progenitor cells (NPC-Astros), particularly in their neuroprotective properties. When grafted into brains subjected to global ischaemia, Olig2PC-Astros exhibit superior neuroprotective effects and improved behavioural outcome compared to NPC-Astros. Thus, this new paradigm of human astroglial differentiation is useful for studying the heterogeneity of human astroglia, and the unique Olig2PC-Astros may constitute a new cell therapy for treating cerebral ischaemia and other neurological diseases. Astroglia are heterogeneous in phenotype and not all astrocytes are equivalent in their ability to repair injured brain. Here, the authors show that two defined subtypes of astroglia generated from hESC-derived Olig2-positive versus Olig2-negative neural progenitors, exhibit distinct properties and neuroprotective effects.
