胚胎神经上皮和成人室下区(SVZ)干细胞和祖细胞表达巢蛋白。我们对一个转基因株系进行了表征,该转基因株系表达由巢蛋白启动子的第二个内含子增强子特异性针对神经组织的增强型绿色荧光蛋白(eGFP),该增强子具有几个新特征。在胚胎发生过程中,背侧端脑含有许多 eGFP+ 细胞,腹侧端脑含有少量 eGFP+ 细胞。 eGFP+ 细胞发现于出生后和成人神经源性区域。 SVZ 中的 eGFP+ 细胞表达多种表型标记、胶质纤维酸性蛋白、Dlx 和神经母细胞特异性分子,表明转基因是通过谱系表达的。皮质损伤后 SVZ 中的 eGFP+ 细胞数量增加,表明该细胞系可用于探测损伤后神经发生。在非神经源性区域,eGFP 在少突胶质细胞祖细胞中强烈表达,但在星形胶质细胞中则不然,即使它们具有反应性。这种 eGFP+ 小鼠将促进增殖性神经上皮和成体神经发生以及实质少突胶质细胞的研究。
Embryonic neuroepithelia and adult subventricular zone (SVZ) stem and progenitor cells express nestin. We characterized a transgenic line that expresses enhanced green fluorescent protein (eGFP) specified to neural tissue by the second intronic enhancer of the nestin promoter that had several novel features. During embryogenesis, the dorsal telencephalon contained many and the ventral telencephalon few eGFP+ cells. eGFP+ cells were found in postnatal and adult neurogenic regions. eGFP+ cells in the SVZ expressed multiple phenotype markers, glial fibrillary acidic protein, Dlx, and neuroblast-specific molecules suggesting the transgene is expressed through the lineage. eGFP+ cell numbers increased in the SVZ after cortical injury, suggesting this line will be useful in probing postinjury neurogenesis. In non-neurogenic regions, eGFP was strongly expressed in oligodendrocyte progenitors, but not in astrocytes, even when they were reactive. This eGFP+ mouse will facilitate studies of proliferative neuroepithelia and adult neurogenesis, as well as of parenchymal oligodendrocytes.
