Extracellular Matrix in Animals

La Matriz Extracelular
La Matriz Extracelular
Overview In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). ...
Glicosaminoglicanos
Glicosaminoglicanos
Glycosaminoglycans (GAGs), also known as mucopolysaccharides, are long and linear polymers comprising of specific repeating disaccharides - the amino ...
Los colágenos son las principales proteínas estructurales de la MEC
Los colágenos son las principales proteínas estructurales de la MEC
Three main types of fibers are secreted by fibroblasts: collagen fibers, elastic fibers, and reticular fibers. Collagen fiber is made from fibrous protein ...
Colágeno asociado a fibrillas
Colágeno asociado a fibrillas
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated ...
La elastina es responsable de la elasticidad de los tejidos
La elastina es responsable de la elasticidad de los tejidos
Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will ...
Las fibronectinas conectan las células con la MEC
Las fibronectinas conectan las células con la MEC
Fibronectin is an adhesive glycoprotein present in the extracellular matrix of embryogenic and adult tissue. These molecules primarily aid in regulating ...
Proteoglicanos y glicoproteínas de la matriz
Proteoglicanos y glicoproteínas de la matriz
Proteoglycans are extensively glycosylated proteins, commonly found in the extracellular matrix, interwoven with collagen fibers. Hyaline cartilage, the ...
Papel de las metaloproteasas de la matriz en la degradación de la MEC
Papel de las metaloproteasas de la matriz en la degradación de la MEC
Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for ...
La lámina basal es la forma especializada de ECM
La lámina basal es la forma especializada de ECM
The basal lamina is a thin extracellular layer that lies underneath the cells and separates them from other tissues. The three layers of the basal lamina ...
Las lamininas son las proteínas adhesivas de la lámina basal
Las lamininas son las proteínas adhesivas de la lámina basal
Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. ...
Colágeno tipo IV de la lámina basal
Colágeno tipo IV de la lámina basal
Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen  ...
