文题释义:
间充质干细胞治疗慢性阻塞性肺病:
在组织替代工程中,诱导间充质干细胞分化为肺泡上皮细胞,用于修复损伤肺组织逐渐成为研究热点。研究发现,间充质干细胞移植能减轻肺气肿大鼠肺部炎症与病理改变,但间充质干细胞向肺上皮细胞分化比例低严重限制干细胞移植疗效。
Wnt/β-catenin信号通路:是高度保守的信号传导途径,参与调控胚胎早期发育、成体组织的稳态维持,也对间充质干细胞自我更新及多向分化等多种生物学过程具有重要调控作用。通过对Wnt/β-catenin信号通路研究的深入,有望解决间充质干细胞移植过程中遇到的难题,如细胞存活时间短、分化比例低等。然而,通过整理及分析文献发现,①Wnt/β-catenin信号通路对调控间充质干细胞向肺上皮细胞分化具有重要作用,但是诱导条件不同,对Wnt/β-catenin信号通路的调控效应是不一样的;②Wnt/β-catenin信号通路极易受诱导条件等外界因素影响。此外,Wnt/β-catenin信号通路调控间充质干细胞移植修复慢性阻塞性肺病的安全性如何,还需要进一步研究观察。

 

摘要
背景:
研究发现Wnt/β-catenin信号通路在间充质干细胞增殖、分化过程中具有重要调控效应。因此,间充质干细胞移植过程中遇到的难题,如细胞存活时间短、分化比例低等,有望通过调控Wnt/β-catenin信号通路来找到解决方案,让干细胞移植为慢性阻塞性肺病提供治疗新希望。
目的:对Wnt/β-catenin信号通路调控间充质干细胞向肺泡上皮细胞分化在慢性阻塞性肺病修复中的机制及研究进展进行综述。
方法:由第一作者在PubMed、Elsevier、Medline等外文数据库及中国知网、万方及中国生物医学文献数据库等中文数据库检索2007至2017年的相关文献。中文检索词:间充质干细胞、慢性阻塞性肺疾病、Wnt/β-catenin信号通路、肺泡上皮细胞分化;英文检索词:Chronic Obstructive Pulmonary Disease,Wnt/β-catenin signaling pathway,Mesenchymal Stem Cells (MSCs),pulmonary epithelial differentiation。经过筛选,保留50篇文献进行进一步分析。
结果与结论:Wnt/β-catenin信号通路有望打破间充质干细胞移植向肺上皮细胞分化率低的局限。慢性阻塞性肺疾病患者的肺脏环境复杂,而Wnt/β-catenin信号通路极易受诱导条件等外界因素影响,不同诱导条件对Wnt/β-catenin信号通路的调控效应是不一样的。因此,Wnt/β-catenin信号通路调控间充质干细胞向肺上皮细胞分化与间充质干细胞移植修复慢性阻塞性肺病的研究仍任重道远。

Abstract:

BACKGROUND: Wnt/β-catenin signaling pathway plays an important role in the proliferation and differentiation of mesenchymal stem cells (MSCs). Therefore, the problems encountered during MSCs transplantation, such as low differentiation rate and short survival time, are expected to find a solution by regulating the Wnt/β-catenin signaling pathway, making MSCs transplantation become a new hope of the treatment of chronic obstructive pulmonary disease (COPD).
OBJECTIVE: To summarize the progress in Wnt/β-catenin signaling pathway that regulates MSCs to differentiate into epithelial cells in the treatment of COPD and the relevant mechanisms.
METHODS: PubMed, Elsevier, Medline, CNKI, WanFang, and CBMdisc databases were retrieved for relevant articles published from 2007 to 2017. The keywords were “chronic obstructive pulmonary disease; Wnt/β-catenin signaling pathway; mesenchymal stem cells (MSCs); pulmonary epithelial differentiation” in Chinese and English, respectively. After literature screening, 50 eligible articles were further analyzed.
RESULTS AND CONCLUSION: The Wnt/β-catenin signaling pathway is expected to reverse the low differentiation of MSCs into lung epithelial cells. COPD patients have a complex lung environment, and Wnt/β-catenin signaling pathway is extremely sensitive to the environmental factors. In addition, the regulation by Wnt/β-catenin signaling pathway is varied under different induction conditions. Therefore, enormous investigations are needed to clarify the regulation of the differentiation of MSCs into lung epithelial cells by the Wnt/β-catenin signaling pathway in the treatment of COPD.
