The extracellular matrix (ECM) is a crucial component of the stem cell microenvironment, or stem-cell niches, and contributes to the regulation of cell behavior and fate. Accumulating evidence indicates that different types of stem cells possess a large variety of molecules responsible for interactions with the ECM, mediating specific epigenetic rearrangements and corresponding changes in transcriptome profile. Signals from the ECM are crucial at all stages of ontogenesis, including embryonic and postnatal development, as well as tissue renewal and repair. The ECM could regulate stem cell transition from a quiescent state to readiness to perceive the signals of differentiation induction (competence) and the transition between different stages of differentiation (commitment). Currently, to unveil the complex networks of cellular signaling from the ECM, multiple approaches including screening methods, the analysis of the cell matrixome, and the creation of predictive networks of protein-protein interactions based on experimental data are used. In this review, we consider the existing evidence regarded the contribution of ECM-induced intracellular signaling pathways into the regulation of stem cell differentiation focusing on mesenchymal stem/stromal cells (MSCs) as well-studied type of postnatal stem cells totally depended on signals from ECM. Furthermore, we propose a system biology-based approach for the prediction of ECM-mediated signal transduction pathways in target cells. Video Abstract.
细胞外基质(ECM)是干细胞微环境或干细胞龛的重要组成部分,有助于调节细胞行为和命运。越来越多的证据表明,不同类型的干细胞具有多种与 ECM 相互作用的分子,介导特定的表观遗传重排和转录组谱的相应变化。ECM 的信号在胚胎和出生后发育、组织更新和修复等所有发育阶段都至关重要。ECM 可以调节干细胞从静止状态到准备感知分化诱导信号的状态的转变(能力),以及不同分化阶段之间的转变(承诺)。目前,为了揭示 ECM 细胞信号的复杂网络,使用了多种方法,包括筛选方法、细胞基质组分析以及基于实验数据创建蛋白质-蛋白质相互作用的预测网络。在这篇综述中,我们考虑了现有的证据,这些证据表明 ECM 诱导的细胞内信号通路对干细胞分化的调节作用,重点关注间充质干细胞(MSCs)作为一种经过充分研究的成体干细胞类型,完全依赖于 ECM 的信号。此外,我们提出了一种基于系统生物学的方法,用于预测靶细胞中 ECM 介导的信号转导途径。视频摘要。
