Interaction of cells with extracellular matrix (ECM) largely defines migration capacity of cells and ways of their dissemination in normal tissue processes and during tumor progression. We review current knowledge about structure of cell adhesions with ECM and their alterations during carcinogenesis. We analyze how changes in structure of cell–matrix adhesions and ECM itself lead to acquisition...

The extracellular matrix (ECM) surrounding cells contains a variety of proteins that provide structural support and regulate cellular functions. Previous studies have shown that decellularized ECM isolated from tissues or cultured cells can be used to improve cell differentiation in tissue engineering applications. In this study we evaluated the effect of decellularized chondrocyte-derived ECM ...

The extracellular matrix (ECM) is a complex and dynamic entity that drives the formation and development of the cardiovascular system, determines critical aspects of cardiovascular performance, and plays key roles in the initiation and progression of abnormal cardiovascular function with aging and disease. Microscopic studies in the late 1700s identified fibrous structures surrounding cells, wh...

The relative roles of ectomycorrhizal (ECM) and saprotrophic communities in controlling the decomposition of soil organic matter remain unclear. We tested the hypothesis that ECM community structure and activity influences the breakdown of nutrient-rich biopolymers in soils, while saprotrophic communities primarily regulate the breakdown of carbon-rich biopolymers. To test this hypothesis, we u...

This study aimed to investigate the cardioprotective effects of intramyocardial injection of heart derived extracellular matrix (ECM) and cardiosphere-derived cells (CDCs) in a rat model of myocardial infarction (MI). ECM and CDCs were collected from the rat heart, and the proliferation, apoptosis and morphology of CDCs maintained on ECM were characterized in vitro. MI model was established in ...

Ectomycorrhizal (ECM) fungi form highly diverse communities in temperate forests, but little is known about their community ecology in tropical ecosystems. Using anatomotyping and rDNA sequencing, ECM fungi were identified on root tips of the introduced Eucalyptus robusta and Pinus caribea as well as the endemic Vateriopsis seychellarum and indigenous Intsia bijuga in the Seychelles. Sequencing...

Epithelial cell behavior is coordinated by the composition of the surrounding extracellular matrix (ECM); thus ECM protein identification is critical for understanding normal biology and disease states. Proteomic analyses of ECM proteins have been hindered by the insoluble and digestion-resistant nature of ECM. Here we explore the utility of combining rapid ultrasonication- and surfactant-assis...

During breast carcinoma progression, the three-dimensional (3D) microenvironment is continuously remodeled, and changes in the composition of the extracellular matrix (ECM) occur. High throughput screening platforms have been used to decipher the complexity of the microenvironment and to identify ECM components responsible for cancer progression. However, traditional screening platforms are typ...

Expression of extracellular matrix (ECM) components during differentiation of pre-existing preadipocytes and preadipocytes recruited by dexamethasone (DEX) was examined with immunocytochemistry in primary cultures of adipose tissue stromal vascular (S-V) cells. Immunocytochemistry showed that a small proportion of preadipocytes (AD-3+) in 24-h cultures (d 0 to 1) contained lipid or expressed EC...
