    Abstract: Methods and systems are disclosed for encapsulating viable cells which produce biologically-active factors. The cells are encapsulated within a semipermeable, polymeric membrane by co-extruding an aqueous cell suspension and a polymeric solution through a common port to form a tubular extrudate having a polymeric outer coating which encapsulates the cell suspension. For example, the cell suspension and the polymeric solution can be extruded through a common extrusion port having at least two concentric bores, such that the cell suspension is extruded through the inner bore and the polymeric solution is extruded through the outer bore. The polymeric solution coagulates to form an outer coating. As the outer coating is formed, the ends of the tubular extrudate can be sealed to form a cell capsule. In one embodiment, the tubular extrudate is sealed at intervals to define separate cell compartments connected by polymeric links.

    Abstract: Living cells such as animal cells which produce biologically active factors are encapsulated within a semipermeable, polymeric membrane such as polyacrylate by co-extruding an aqueous cell suspension and a polymeric solution through a common port having at least one concentric bores to form a tubular extrudate having a polymeric membrane which encapsulates the cell suspension. The cell suspension is extruded through an inner bore and the polymeric solution is extruded through an outer bore while a pressure differential is maintained between the cell suspension and the polymeric solution to impede solvent diffusion from the polymeric solution into the cell suspension. The polymeric solution coagulates to form an outer coating or membrane as the polymeric solution and the cell suspension are extruded through the extrusion port. As the outer membrane is formed, the ends of the tubular extrudate are sealed to form a cell capsule. In one embodiment, the tubular extrudate is sealed at intervals to define separate cell compartments connected by polymeric links. In another embodiment, a cell capsule connected to a tethering filament is formed. The polymeric membrane may contain additives such as a surfactant, an anti-inflammatory agent or an anti-oxidant and can be coated with a protective barrier. The cell suspension may contain nutrients and an anchorage substrate.

    Abstract: Cultures of cells immunoreactive for glial fibrillary acidic protein (GFAP), as well as for the intermediate filament marker nestin were grown in a medium including epidermal growth factor (EGF) and serum. The cultured cells had the morphology of astroglial cells. The cells can be proliferated in adherent or suspension cultures. Depending on the culture conditions, the cells can be induced to differentiate to neurons or glial cells. The cultures can be expanded over a large number of passages during several months, and survive, express an astroglial phenotype and integrate well after transplantation into both neonatal and adult rat forebrain.

    Abstract: An exchange system and a method for trading orders on an exchange market and a related broker workstation. One or more user defined order matrixes allows a user to design a trading strategy by manually, or by means of algorithms using current and/or historical market data, determine trading parameters such as part order size, price level, time delay between consecutive part orders. An order having a total volume and at least one such order matrix associated therewith is received from a market participant. The order matrix specifies predetermined portions of the order's total volume. A first portion of the order's total volume is determined in accordance with the order matrix and information is sent to display the that portion to the market. A next portion of the order's total volume is generated in accordance with the order matrix and information is then sent to display that portion to the market.
