On the importance of extracellular matrix of the skin for efficient 3D cell culture models

The extracellular components of the skin can be divided into fiber-forming structural molecules, nonfiber-forming structural molecules, and “matricellular proteins”. Optimal quantities of different matrix components and their delicate interactions are necessary to maintain normal physiologic properties of the skin. Fiber-forming molecules provide a structure to the ECM by creating a Read more…

The ExtraCellular Matrix: a focus on GlycosAminoGlycans and Hyaluronan

The extracellular matrix (ECM) is a three-dimensional macromolecular network composed of structural proteins (collagens, elastin), adhesion/signalling proteins (fibronectin, laminins), different proteoglycans, glycoproteins and glycosaminoglycans (GAGs). GAGs are structurally complex, but their structure is simply made up of repeating disaccharide building blocks composed of alternating uronic acid and hexosamine units. GAGs Read more…
