Extracellular matrix (ECM) is primarily composed of collagen, glycoproteins (such as laminin, vitronectin, and fibronectin), and proteoglycans. It is crucial for stem cell adhesion and tissue stability by activating signaling pathways through integrins. For effective use in regenerative medicine and cell...

ECM includes collagens, a variety of fibrous proteins of triple-helical coiled coil structure, glycoproteins (laminin, fibronectin), proteoglycans, etc. ECM is linked to the intracellular cytoskeleton by integrins. Without anchorage, most cells succumb to apoptosis. Matrix metalloproteinase modifies the ...
The extracellular matrix (ECM) is a dynamic complex of interwoven fibrils and globular macromolecules, coming together to form the foundation of all biological tissue. Comprising of collagens, glycoproteins, and proteoglycans, as well as associated secreted factors and enzymatic regulators, this supramole...

奥格诺德(ORG)基质胶(Orgmatrix gel)是从富含胞外基质蛋白的小鼠肿瘤中提取出的天然制剂,主要成分是各类细胞外基质成分和生长因子。细胞外基质成分主要包括层粘连蛋白(Laminin)、IV 型胶原蛋白(Col-IV)、巢蛋白(Nidogen/Entactin)、硫酸乙酰肝素蛋白多糖(Heparan Sulfate Proteoglycans)等。主要生长因子成分有类胰岛素生...
One of the most vital synapomorphic properties of metazoans is the presence of an extracellular matrix (ECM), i.e., a complex of proteoglycans, adhesive glycoproteins, and collagens. The genetically controlled ECM mediates between the respective receptors morphogenesis and cell differentiation and is...
