eterotopically Transplanted Hepatocyte Survival Depends on xtracellular Matrix Components
The novel approach of tissue engineering to treat many forms of liver diseases using hepatocytes requires sufficient numbers and sustained survival of the transplanted cells. It has been shown that providing extracellular matrix components extracted from Engelbreth-HolmSwarm cells (EHS-ECMs) to heterotopically transplanted hepatocytes allows significantly greater hepatocyte survival. We investi...
متن کاملCell–cell and cell–matrix interactions
Roles of cell protrusions as initial and dynamic mediators of cell–cell and cell–ECM interactions Filopodia have well-established roles in sampling the local environment and making initial cell–ECM contacts at the leading edge of many cell types. Filopodial-like structures, termed “epithelial zippers,” can mediate initial contacts between epithelial cells that culminate in assembly of cell–cell...
متن کاملA Matrix-valued Point Interactions Model
Abstract. We study a matrix-valued Schrödinger operator with random point interactions. We prove the absence of absolutely continuous spectrum for this operator by proving that away from a discrete set its Lyapunov exponents do not vanish. For this we use a criterion by Gol’dsheid and Margulis and we prove the Zariski denseness, in the symplectic group, of the group generated by the transfer ma...
متن کاملInteractions of Cartilage Extracellular Matrix Macromolecules.
Articular cartilage is a low-friction, load-bearing tissue located at joint surfaces. The extracellular matrix (ECM) of cartilage consists of a fibrous collagen network, which is pre-stressed by the osmotic swelling pressure exerted by negatively charged proteoglycan aggregates embedded in the collagen network. The major proteoglycan is the bottlebrush shaped aggrecan, which forms complexes wit...
متن کاملIntegrin-matrix interactions in the cerebral microvasculature.
The integrity of all organ systems requires faithful interaction between its component cells and the extracellular matrix (ECM). In the central nervous system (CNS), matrix adhesion receptors are uniquely expressed by the cells comprising the microvascular compartment, and by neurons and their supporting glial cells. Cells within the cerebral microvasculature express both the integrin and dystr...
