发现的标志物,以确定肠道干细胞群体和强大的转基因小鼠模型的产生,研究干细胞生理学,导致在干细胞生物学的重大发现。在这篇综述中,我们给出了目前的知识在肠道干细胞(ISCs)领域的概述,突出了最新进展的标志物定义的ISC人口和途径管理肠道干细胞的维持和分化。此外,我们还综述了它们与其他干细胞相关通路的相互作用。最后,我们对这些通路在人类炎症性胃肠道疾病中的改变进行了概述。我们强调了不同途径之间发生的复杂的相互作用网络,并透视了在维持肠道内稳态中发生的许多调节层。了解ISCs参与炎症性疾病可能会导致新的治疗方法来治疗炎症性GI病变,如IBD和乳糜泻,并可能揭示导致炎症性慢性疾病中发育不良和癌症发病机制的分子机制。
The discovery of markers to identify the intestinal stem cell population and the generation of powerful transgenic mouse models to study stem cell physiology have led to seminal discoveries in stem cell biology. In this review we give an overview of the current knowledge in the field of intestinal stem cells (ISCs) highlighting the most recent progress on markers defining the ISC population and pathways governing intestinal stem cell maintenance and differentiation. Furthermore we review their interaction with other stem cell related pathways. Finally we give an overview of alteration of these pathways in human inflammatory gastrointestinal diseases. We highlight the complex network of interactions occurring among different pathways and put in perspective the many layers of regulation that occur in maintaining the intestinal homeostasis. Understanding the involvement of ISCs in inflammatory diseases can potentially lead to new therapeutic approaches to treat inflammatory GI pathologies such as IBD and celiac disease and could reveal the molecular mechanisms leading to the pathogenesis of dysplasia and cancer in inflammatory chronic conditions.
