基因启动子、增强子和阻遏子结合元件的发现和鉴定是神经科学的一个重要研究领域。在这里,胚胎干细胞及其神经衍生物作为本研究的模型系统的适用性进行了研究。将已在转基因小鼠中验证的三种神经转基因构建体(来自Mnx1、Fabp7和tuba1a基因)作为稳定的转基因插入胚胎干细胞中。将这些转基因胚胎干细胞分化为神经培养物,并确定在一系列诱导条件下的转基因表达模式。对于三种转基因中的每一种,表达模式与转基因小鼠实验预测的相匹配。结果表明,胚胎干细胞及其神经衍生物构成了一个有前途的模型,用于研究控制细胞和时间特异性神经基因转录的机制。
Discovery and characterization of gene promoters, enhancers and repressor binding elements is an important research area in neuroscience. Here, the suitability of embryonic stem cells and their neural derivatives as a model system for this research is investigated. Three neural transgenic constructs (from the Mnx1, Fabp7, and tuba1a genes) that have been validated in transgenic mice were inserted into embryonic stem cells as stable transgenes. These transgenic embryonic stem cells were differentiated into neural cultures and the pattern of transgene expression across a series of inducing conditions determined. The pattern of expression matched that predicted from transgenic mouse experiments for each of the three transgenes. The results show that embryonic stem cells and their neural derivatives comprise a promising model for investigating the mechanisms that control cell- and temporal- specific neural gene transcription.
