文题释义:
物理因素:
干细胞生长的物理微环境对细胞形状、大小、排列方向、分化方向有重要影响,可以通过加载机械负荷、施加电刺激、调节基质硬度和拓扑结构、三维培养等物理方法来模拟心肌细胞生长的微环境,促进干细胞源心肌细胞的成熟。
干细胞心肌向分化:常见的干细胞如胚胎干细胞、诱导多能干细胞、间充质干细胞、心脏干细胞等具有心肌向分化潜能。这些干细胞产生的心肌细胞有明确的心脏表型,在体外和体内都能明显增殖,可以用于建立心脏药理模型以及心肌细胞治疗。

 

摘要
背景:
寻找提高干细胞心肌向分化成熟度的方法成为心脏疾病治疗研究的热点。
目的:总结和分析了提高干细胞心肌向分化成熟度的物理刺激方法及研究新进展。
方法:以“干细胞、心肌细胞、机械刺激、电刺激、基质、三维培养、成熟度”为中文关键词,以“stem cell,cardiomyocyte,mechanical stimulation,electrical stimulation,substrate,three-dimensional culture, maturity”为英文关键词,使用计算机检索PubMed、中国期刊全文数据库(CNKI)等数据库,纳入方法规范、逻辑严谨、与物理因素刺激干细胞心肌向分化成熟相关的研究性论文,排除个案研究、方案设计不合理的研究、无规范严谨纳入标准的综述性研究及与论述主题无关的研究。
结果与结论:通过检索文献,总结了提高干细胞心肌向分化成熟度的各种物理刺激因素,包括其作用机制及研究进展,为临床使用干细胞移植治疗心脏疾病带来了全新的方法,但目前的研究仍存在一些需要解决的问题,如移植细胞死亡、免疫排斥反应、心律失常和致瘤等,限制了其在临床的应用。

Abstract:

BACKGROUND: Methods for improving the myocardial differentiation of stem cells have become a hot topic in the treatment of heart diseases.
OBJECTIVE: To summarize and analyze the physical stimulation methods and research advances in improving the myocardial differentiation of stem cells.
METHODS: A online computer search of PubMed, Chinese Journals Full-text Database (CNKI) and other literature databases was conducted using the keywords of “stem cell, cardiomyocyte, mechanical stimulation, electrical stimulation, substrate, three-dimensional culture, maturity” in English and Chinese, respectively. Research literature related to normative, logical and rigorous methods as well as physical factors for stimulating myocardium maturation differentiated from stem cells. Case studies, studies with no rational standard design program, review with no rigorous inclusion criteria, and studies having nothing to do with the topic were excluded.
RESULTS AND CONCLUSION: Through the literature search, a variety of physical stimuli, mechanisms of action and research progress have been summarized to improve myocardial differentiation and maturity of stem cells. The use of stem cell transplantation for the treatment of heart disease has brought new methods for clinical use, but there are still some problems to be solved, such as transplanted cell death, immune rejection, arrhythmia and tumorigenesis, which have limited the clinical application of stem cells.
