摘要:

文题释义:

多向分化潜能:指细胞具有自我更新、持续增殖分裂并可以在不同微环境影响下向相应方向分化为多种组织的能力,即经过不同细胞因子的诱导,能够分化为脂肪、骨、软骨、肌肉、血管内皮、肝、神经等细胞系类型,一般为干细胞或类干细胞所具备的能力。

组织工程种子细胞:应用组织工程方法再造组织和器官所用的各类细胞,其中包括分化成熟的成体细胞和具有分化潜能的干细胞,应满足以下几点:采用微创或无创手段即可获取的组织,分裂增殖能力强,功能旺盛,无或仅有极微弱的免疫排斥反应,能够连续传代,且传代培养后不发生形态、功能及遗传物质的改变。

背景:组织工程技术的出现可以从根本上解决组织、器官的修复与重建问题,其中种子细胞的选择和应用则成为当前研究的热难点,成纤维细胞是各组织工程研究的热门选择。

目的:总结分析成纤维细胞的生物学特性、自身分化潜能以及对干细胞分化增殖的影响。

方法:运用计算机检索中国期刊全文数据库(2015至2019年)和PubMed数据库(2005至2019年)中有关于成纤维细胞生物学特性以及多向分化潜能的相关文献,并进行系统的归纳、总结和分析,对成纤维“干性”的研究新进展进行全面阐述。

结果与结论:成纤维细胞代谢旺盛、增殖能力强,具有合成和分泌蛋白质的功能,在不同微环境中可分化为不同细胞,拥有与干细胞一样强大的多向分化潜能,因此常运用于转分化、细胞培养、损伤修复以及组织工程,其中促进干细胞增殖及诱导分化的作用尤为显著,今后应最大化利用成纤维细胞生物学优势与干细胞共培养,为组织工程学提供种子细胞,为临床中创伤的修复提供更佳思路。

Abstract:

BACKGROUND: Tissue engineering technology has emerged to solve the repair and reconstruction of tissues and organs. The selection and application of seed cells become an issue of concern. Fibroblasts are a popular choice in various tissue engineering studies.

OBJECTIVE: To summarize the biological characteristics of fibroblasts, their multi-potential differentiation and their effects on the proliferation and differentiation of stem cells.

METHODS: A computer-based research of CNKI (2015-2019) and PubMed (2005-2019) databases was performed for the articles about the biological characteristics of fibroblasts and multipotential differentiation. The articles were systematically summarized and analyzed. The newest research process of multi-potential differentiation of fibroblasts was reviewed.

RESULTS AND CONCLUSION: Fibroblasts hold strong metabolism and proliferation abilities, which can synthesize and secrete protein. Fibroblasts can differentiate into different cells under different environments, and exhibit the same strong multi-potential differentiation with stem cells. Therefore, it is commonly used in the transdifferentiation, cell culture, injury repair and tissue engineering, and their effects on promoting proliferation and inducing differentiation of stem cells are particularly significant. We should fully utilize the biological characteristics and multi-potential differentiation of fibroblasts, and co-culture of fibroblasts with stem cells can provide seed cells for tissue engineering, which further provide an idea for traumatic repair in clinic.

Key words: fibroblasts, biological characteristics, stem cells, proliferation and differentiation, microenvironment
