extracellularmatrix, etc ; blood; nanocarriers; neoplasms; Show all 4 Subjects
Abstract:
... Nanocarriers have been widely employed in preclinical studies and clinical trials for the delivery of anticancer drugs. The most important causes of failure in clinical translation of nanocarriers is their inefficient accumulation and penetration which arises from special characteristics of tumor microenvironment such as insufficient blood supply, dense extracellular matrix, and elevated interstit ...
extracellularmatrix, etc ; birds; collagen; dermis; embryogenesis; Show all 5 Subjects
Abstract:
... During vertebrate embryogenesis, cell collectives engage in coordinated behavior to form tissue structures of increasing complexity. In the avian skin, assembly into follicles depends on intrinsic mechanical forces of the dermis, but how cell mechanics initiate pattern formation is not known. Here, we reconstitute the initiation of follicle patterning ex vivo using only freshly dissociated avian d ...
extracellularmatrix, etc ; hydrostatic pressure; mechanochemistry; morphogenesis; Show all 4 Subjects
Abstract:
... Morphogenesis, the process by which tissues develop into functional shapes, requires coordinated mechanical forces. Most current literature ascribes contractile forces derived from actomyosin networks as the major driver of tissue morphogenesis. Recent works from diverse species have shown that pressure derived from fluids can generate deformations necessary for tissue morphogenesis. In this revie ...

extracellularmatrix, etc ; biofilm; immune system; therapeutics; yeasts; Show all 5 Subjects
Abstract:
... Biofilms are highly-organized microbial communities attached to a biotic or an abiotic surface, surrounded by an extracellular matrix secreted by the biofilm-forming cells. The majority of fungal pathogens contribute to biofilm formation within tissues or biomedical devices, leading to serious and persistent infections. The clinical significance of biofilms relies on the increased resistance to co ...
extracellularmatrix, etc ; biocompatible materials; hydrogels; medicine; therapeutics; Show all 5 Subjects
Abstract:
... Mesenchymal stem cells (MSCs) have been increasingly recognized as a resource for disease treatment and regenerative medicine. Meanwhile, the unique chemical and physical properties of hydrogels provide innate advantages to achieve high quality MSCs on a large scale. Tremendous kinds of biomaterials have been employed to form hydrogels providing a controllable microenvironment for culturing MSCs. ...
extracellularmatrix, etc ; actin; epithelium; fibroblasts; medicine; morphogenesis; myosin; Show all 7 Subjects
Abstract:
... The mechanism by which stromal cells fill voids in injured tissue remains a fundamental question in regenerative medicine. While it is well-established that fibroblasts fill voids by depositing extracellular matrix (ECM) proteins as they migrate toward the wound site, little is known about their ability to adopt an epithelial-like purse-string behavior. To investigate fibroblast behavior during ga ...
extracellularmatrix, etc ; arthropods; endoparasites; integument; lifestyle; parasitism; ultrastructure; Show all 7 Subjects
Abstract:
... Specialized morphology of diverse parasitic crustaceans reflects their adaptations to an endoparasitic lifestyle. Rhizocephalan barnacles are one of the most highly modified obligatory parasites of other crustaceans. Comprehension of the functional morphology of rhizocephalans could elucidate the main evolutionary trends not only inside parasitic barnacles, but in parasitism as a whole. Despite th ...
extracellularmatrix, etc ; Drosophila; basement membrane; morphogenesis; oogenesis; secretion; Show all 6 Subjects
Abstract:
... The basement membrane (BM) - a specialized sheet of extracellular matrix present at the basal side of epithelial cells - is critical for the establishment and maintenance of epithelial tissue morphology and organ morphogenesis. Moreover, the BM is essential for tissue modeling, serving as a signaling platform, and providing external forces to shape tissues and organs. Despite the many important ro ...
extracellularmatrix, etc ; brain; cytokines; glycosaminoglycans; humans; lungs; proteoglycans; research; Show all 8 Subjects
Abstract:
... A wide variety of diseases throughout the mammalian organism is characterized by abnormal deposition of various components of the extracellular matrix (ECM), including the heterogeneous family of glycosaminoglycans (GAGs), which contribute considerably to the ECM architecture as part of the so-called proteoglycans. The GAG's unique sulfation pattern, derived from highly dynamic and specific modifi ...
extracellularmatrix, etc ; biocompatible materials; cations; drugs; endothelial cells; hydrogels; Show all 6 Subjects
Abstract:
... In vitro models are valuable tools for applications including understanding cellular mechanisms and drug screening. Hydrogel biomaterials facilitate in vitro models by mimicking the extracellular matrix and in vivo microenvironment. However, it can be challenging for cells to form tissues in hydrogels that do not degrade. In contrast, if hydrogels degrade too much or too quickly, tissue models may ...
extracellularmatrix, etc ; actin; bone marrow; cell proliferation; hydrogels; medicine; Show all 6 Subjects
Abstract:
... Matrix stiffness and fibrous structure provided by the native extracellular matrix have been increasingly appreciated as important cues in regulating cell behaviors. Recapitulating these physical cues for cell fate regulation remains a challenge due to the inherent difficulties in making mimetic hydrogels with well-defined compositions, tunable stiffness, and structures. Here, we present two serie ...

Abstract:
... Microscopical fungi, both molds and yeasts, play a relevant role in the food industry. Despite having beneficial applications in the biotechnological area and being an alternative in industrial enzyme production, fungi also present a potential for food deterioration. These microorganisms are excellent candidates for biofilm formation, producing an extracellular matrix capable of conferring resista ...
extracellularmatrix, etc ; disease progression; fibroblasts; metastasis; neoplasms; phenotype; therapeutics; Show all 7 Subjects
Abstract:
... Reciprocal interactions between cancer cells and stromal cells in the tumor microenvironment (TME) are essential for full‐blown tumor development. Carcinoma‐associated fibroblasts (CAFs) are a key component of the TME together with a wide variety of stromal cell types including vascular, inflammatory, and immune cells in the extracellular matrix. CAFs not only promote tumor growth, invasion, and m ...

Abstract:
... Matrix metalloproteinase-2 (MMP-2) and cluster of differentiation 147 (CD147) both play important roles in the development of kidney fibrosis, and CD147 can induce the production and activation of MMP-2. In the early stage of kidney fibrosis, MMP-2 promotes extracellular matrix (ECM) production and accelerates the development of kidney fibrosis, while in the advanced stage, MMP-2 activity decrease ...

Abstract:
... Cardiovascular/heart tissue and cells are subjected to dynamic forces from very early development, without pause, for the entire life of the animal or person and are characterized by being very sensitive to the mechanical properties of the surrounding tissue. Most cardiovascular diseases are characterized by important modifications that occur at the level of extracellular matrix (ECM) components t ...

Abstract:
... Elastic fibers are an essential part of the pulmonary extracellular matrix (ECM). Intact elastin is required for normal function and its damage contributes profoundly to the etiology and pathology of lung disease. This highlights the need for novel lung-specific imaging methodology that enables high-resolution 3D visualization of the ECM. We consider elastin’s involvement in chronic respiratory di ...

Abstract:
... Mesenchymal stem cells (MSCs) are a major component of the tumor microenvironment (TME) and play an important role in tumor progression. MSCs remodel the extracellular matrix, participate in the epithelial–mesenchymal transition, promote the spread of metastases, and inhibit antitumor immune responses in the TME; however, there are also data pertaining to the antitumor effects of MSCs. MSCs activa ...

Abstract:
... Severe spinal cord injury causes permanent loss of function and sensation throughout the body. The trauma causes a multifaceted torrent of pathophysiological processes which ultimately act to form a complex structure, permanently remodeling the cellular architecture and extracellular matrix. This structure is traditionally termed the glial/fibrotic scar. Similar cellular formations occur following ...
