恒河猴和人类胚胎干细胞(ESC)是相似的,使恒河猴ESC成为一个适当的临床前同种异体移植模型,用于完善干细胞疗法。恒河猴胚胎干细胞衍生的神经祖细胞(NP)在临床前应用中的使用将得到加强,如果神经衍生过程是可扩展的,没有污染的胚胎干细胞或非神经细胞。在这项研究中,我们已经量化的恒河猴ESC分化为统一的NP使用简单的无饲养层贴壁培养的时间基因表达的变化。纳米颗粒表现出显着的上调神经特异性基因和下调多能性基因。此外,Hu、MAP2和Tuj1的表达表明NP可以形成有丝分裂后神经元。这项研究代表了一种简单且可扩展的方法,用于生产粘附的灵长类动物NP,用于基于神经细胞的治疗的临床前测试。
Rhesus and human embryonic stem cells (ESCs) are similar, making rhesus ESCs an appropriate preclinical allograft model for refining stem cell therapies. Use of rhesus ESC-derived neural progenitors (NPs) in preclinical applications will be enhanced if the neural derivation process is scalable and free from contaminating ESCs or nonneural cells. In this study, we have quantified temporal gene expression changes of rhesus ESC differentiated to uniform NPs using simple feeder-free adherent cultures. NPs exhibited a significant up-regulation of neural-specific genes and a downregulation of pluripotency genes. Additionally, expression of Hu, MAP2, and Tuj1, shows that NPs can form post-mitotic neurons. This study represents a simple and scalable means of producing adherent primate NPs for preclinical testing of neural cell-based therapy.
