项目摘要
Abstract
The enteric nervous system (ENS) accomplishes a broad range of activities that rely on a remarkably
diverse population of neuronal and glial subtypes. Loss of specific cell types, such as nitric oxide (NO)
producing neurons (nitrergic neurons) leads to enteric neuropathies associated with dysmotility
disorders including esophageal achalasia, gastroparesis and infantile hypertrophic pyloric stenosis. The
underlying pathophysiology of these disorders have remained largely unknown due to limitations of
currently available cellular models. We have recently reported a new alternative approach for
differentiation of ENS lineages from human pluripotent stem cells under fully defined conditions,
providing a unique and reliable framework for ENS disease modeling and drug discovery. Taking
advantage of high content chemical compound screening in combination with fate map reconstruction
guided by single cell transcriptomics, here we propose a new strategy for efficient derivation and
prospective isolation of enteric nitrergic neurons. This system will provide a unique in vitro model for
identification of pharmacological regulator of these neurons and dissection of cellular mechanisms that
underlie GI dysmotilty. We will further evaluate the potential of these neurons in transplantation studies
aimed at the ultimate development of cell-based treatment of enteric neuropathies related to the loss
of nitrergic neurons.
摘要:

肠胃病和神经系统疾病(ENS)可以完成一系列广泛的医疗活动,而这些活动往往依赖于一项医疗服务。
不同类型的神经细胞和神经胶质细胞亚型。某些特定细胞亚型的丢失,如一氧化氮(NO)。
产生硝酸能神经元可导致与运动障碍相关的肠道神经病变。
疾病包括食道失弛缓症、胃轻瘫和婴儿肥厚性幽门狭窄。
由于疾病的局限性,这些疾病的潜在病理生理学机制仍在很大程度上是未知的。
目前有可用的移动通信模式。我们最近报道了一种全新的移动通信替代方法。
在完全明确的条件下,从人类多能干细胞中分离出的干细胞系的分化能力。
为人类疾病建模和药物研发提供了一个独特的、可靠的技术框架。
高化学成分的优势:化合物的筛选与命运地图的重建相结合。
在单细胞和转录组学的指导下,在这里,我们可以提出一种新的基因战略,以实现高效的基因派生。
该系统的建立将为临床应用提供一种独特的体外培养模型。
药理学监管机构对这些神经细胞的鉴定报告,以及对其细胞调控机制的剖析。
这是胃肠道疾病的基础。我们将进一步评估这些神经元在移植和研究中的潜在价值。
旨在为以细胞为基础的肠道神经疾病的最终治疗方案提供更好的解决方案,以减少损失。
硝酸能神经元。
