The extracellular matrix or ecm essay

Proteoglycans[ edit ] Glycosaminoglycans GAGs are carbohydrate polymers and mostly attached to extracellular matrix proteins to form proteoglycans hyaluronic acid is a notable exception, see below. Proteoglycans may also help to trap and store growth factors within the ECM. Described below are the different types of proteoglycan found within the extracellular matrix. Heparan sulfate[ edit ] Heparan sulfate HS is a linear polysaccharide found in all animal tissues.

Archaeology and Old Norse studies Research interests: Viking Age; Scandinavia; Viking archaeology; Old Norse literature and religion; magic and ritual in the Early Middle Ages; funerary archaeology; gender studies; medieval warfare Planned research project: Armed Females in Viking Archaeology and Old Norse Literature" This project will examine the motif of female warriors in the Viking Age through an interdisciplinary approach to archaeological materials and textual sources.

In traditional studies, Norse women were seen as confined mainly to the domestic sphere, with only a very limited role in the social arena. A number of written accounts describe women who actively engaged in martial activities, led men, and fought savagely at the forefront of armies.

Archaeological excavations have also revealed graves of women buried with weapons, and there are a wide range of iconographic depictions of armed females. Was it typical to encounter female fighters in Viking warbands, or was this a rare occurrence regarded as a form of social deviancy and transgression of norms?

What other circumstances lead women to take up arms? To find answers to these questions, this project will draw from the rich textual heritage of the North, critically combining it with specialist studies of archaeological materials, including a comprehensive museum-based analysis of funerary evidence from the Viking Age.Dr.

Feb 08,  · A substantial portion of the volume of tissues is extracellular space, which is largely filled by an intricate network of macromolecules constituting the extracellular matrix, ECM. The ECM is composed of two major classes of biomolecules: glycosaminoglycans (GAGs), most often covalently linked to protein forming the proteoglycans, and fibrous.

Using synthetic foam type materials to mimic the natural process – known as the extracellular matrix or ECM – scientists, from the University of Sheffield and University of California San Diego, created the random stickiness required for stem cells to properly adhere.

In no tissue is the extracellular matrix so well defined - or so easily studied - as in connective tissue, where the extracellular matrix is frequently more plentiful than the cells. Found.

A 3D cell culture is an artificially created environment in which biological cells are permitted to grow or interact with their surroundings in all three dimensions.

Unlike 2D environments (e.g. a petri dish), a 3D cell culture allows cells in vitro to grow in all directions, similar to how they would in vivo.

These three-dimensional cultures are usually grown in bioreactors, small capsules in.
