Abstract: The present invention provides a bionic organ device comprises a porous thermo-responsive layer, a cell culturing layer, a flow channel and a controlling module. The thermo-responsive layer is formed by weaving a fiber made of/from a plurality of thermo-responsive polymers and has a first surface and a second surface opposite to the first surface. The cell culturing layer is formed on the first surface of the thermo-responsive layer. The flow channel has an accommodating space for accommodating the thermo-responsive layer, wherein the flow channel is utilized to allow a flow passing through the second surface inside the flow channel. The controlling module is utilized to allow the flows having different flow temperatures passing through the second surface in the flow channel so as to control a temperature variation of the thermo-responsive layer around critical temperature whereby an expansion and contrast motion of the thermo-responsive layer can be generated.

Abstract: A device and method for cultivating cells are provided, wherein a cell cultivating layer is formed on a surface of a substrate, and a temperature-responsive layer having a plurality of temperature-responsive polymer with magnetic objects is formed on a surface of the cell cultivating layer. When a controlling characteristic exerted on the temperature-responsive layer is varied, a plurality of cells can be adhered on the cell cultivating layer or detached therefrom. When the device is utilized, a temperature control step is operated to control environmental temperature at a first temperature for inducing temperature-responsive polymers becoming hydrophobic whereby the plurality of cells are adhered on the cell cultivating layer. In addition, the alternating magnetic field is utilized to rise temperature of the temperature-responsive polymers so that the plurality of cells can be kept being adhered on the cell cultivating layer at a second temperature lower than the first temperature.
