    摘要： The present invention provides for the coaxial encapsulation of a plurality of cells in a single elongated compartment. By this encapsulation, the cells are protected by at least one layer of separation material and kept in close contact, which leads to a better vitality of the encapsulated cells and consequently results in higher chances to form microtissue. Methods and devices for the production of such encapsulated cell compartments are disclosed as well as medical uses of such compartments in cell, tissue therapy and tissue engineering.

    摘要： The invention relates to a valve for opening and closing a channel (3) of a microfluidic system, respectively. According to the invention, the valve comprises an actuation medium (2) that undergoes a volume change with changing temperature; and a heater arrangement (5) for generating a temperature gradient in the actuation medium (2) with respect to the actuation medium's (2) distance relative to the channel (3); wherein due to an expansion or a contraction of the actuation medium (2) the channel (3) is closed or opened, respectively. When the heater arrangement (5) is activated in such a way that a higher temperature is generated in the actuation medium (2) which is nearer to the channel (3) and a lower temperature is generated in the actuation medium (2) which is further away from the channel (3) the valve can be closed and vice versa. Accordingly, such a valve for a microfluidic system is provided which can be reliably actuated during a long time of use.
