Abstract: A bioprinter for fabricating three-dimensional (3D) cell constructs, the bioprinter comprising one or more holding reservoirs for holding a fluid sample; a printstage for holding a sample container and supporting a substrate on which a 3D cell construct is to be printed; a sample loading system in fluid communication with the one or more holding reservoirs, the sample loading system configured to load a sample from a sample container into the one or more holding reservoirs; a pump in fluid communication with the sample loading system, the pump configured to draw the sample out of a sample container and pump the sample into the one or more holding reservoirs; and a droplet dispensing system in fluid communication with the one or more reservoirs, the droplet dispensing system configured to print sample droplets from the one or more reservoirs onto a substrate supported by the printstage.

Abstract: A method, software tool and system for communicating data between components in a client computer system is provided. The client computer system has a user interface for displaying a page comprising content rendered by a plurality of components. A property broker is provided which maintains a registry of linked source and destination data fields of components of the client computer system. The property broker is notified when a user request is detected by a component registered with the property broker, and a set of components registered with the property broker is then notified of the start of a communication phase. The user request is processed by the actioned component and the value of each source data field updated during processing of the user request is communicated to each component having a linked destination data field. The property broker notifies the set of components when the communications phase has ended, and at least one component then renders content for display.
