Provided are: a production device by which a cell structure having a three-dimensional structure is produced using a plurality of linear members; a production system therefor; and a production method therefor. The production device 100 comprises a top plate 110, pins 120A to 120D, a first slide plate 130, a second slide plate 140, a stopper 150, a base plate 160, an outer peripheral needle-shaped member 170 and an inner peripheral needle-shaped member 180. Cell aggregates 400 are put into a three-dimensional tubular space S1 that is defined by the outer peripheral needle-shaped member 170 and the inner peripheral needle-shaped member 180. Then, the top plate 110 is pressed downward on the accumulated cell aggregates 400. Thus, the cell aggregates 400 are immersed in a culture solution 210 and stuck together so that a tubular cell structure 500 is produced using the three-dimensional space S1 as a mold.

The invention discloses a bioreactor with a vessel defining an inner volume, agitation means and at least one addition tube, wherein a delivery orifice in the addition tube is located within the inner volume and a check valve is arranged in proximity of the delivery orifice for allowing flow of a fluid in the direction from the addition tube into the inner volume of the vessel and blocking flow in the reverse direction.

A cell culture chamber device for growing cell cultures and tissues. The device includes: an enclosure containing a cell culture media, the enclosure being defined partly by a first end, a second end, and a connecting wall. The first end or a part or window thereof is substantially transparent, and the second end and/or the connecting wall, or a respective part or window thereof, is/are substantially transparent/translucent. The first end is configured to be optically aligned, at least for some period of time or periodically, with the second end and/or with the connecting wall so that light or another illumination or visualisation signal, transmitted through or by the second end and/or through or by the connecting wall into the enclosure is transmitted through the cell culture media and out through the first end to outside the enclosure, and e.g. to outside the cell culture chamber device.

The present invention provides a culture method capable of maturing an organoid through long-term culture, and suitable for producing a conformational organ. The culture method of the present invention is a method for culturing an organoid and/or cells constituting an organ immobilized in a chamber with a culture fluid perfused, and the culture fluid is perfused in such a manner as to generate a turbulent flow in the chamber.

The microfluidic chip according to an embodiment of the present invention may include a plate, a bridge channel formed in intaglio on one side of the plate, an inlet formed through the plate to communicate with one end of the bridge channel, an outlet formed through the plate to communicate with the other end of the bridge channel, and at least one well extending in an outward direction of the plate from the bridge channel to provide a space, wherein the bridge channel may be in the form of a curved line, a bent line, an arc, a circle, a spiral, or a polygon.

The present invention relates generally to a three-dimensional cell and tissue culture system for the female reproductive tract. In particular provided herein the system includes individual female reproductive cultures in a dynamic microfluidic setting or integrated using a microfluidic microphysiologic system. In some embodiments, the present invention provides ex-vivo female reproductive tract integration in a three dimensional (3D) microphysiologic system.

The present invention relates to a novel bioreactor system for preparing an engineered three- dimensional biological tissue construct. The bioreactor system comprises a cultivation chamber that is designed to allow the formation, cultivation and the subsequent testing and/or stimulation of tissue constructs on one or more support elements with a minimum risk of microbial contamination or mechanical damage The invention furthermore relates to a method for preparing an engineered tissue construct using the novel bioreactor system. The invention also relates to the use of the bioreactor system for preparing engineered biological tissue constructs, preferably tissue constructs which are suitable for being used in clinical tissue replacement and reconstructive therapy, drug development, drug screening, toxicity testing, cosmetic studies, safety testing, developmental studies, disease modeling, or food purposes.

Disclosed is a method of constructing a cell sheet using only cells without a support. More particularly, a method of manufacturing a multi-layered cell sheet without a separate lamination step and a cell sheet manufactured by the method are disclosed.

A platform for creating engineered tissues includes a vascular tube that defines a vascular diameter and is configured to receive vascular system seed cells, a non vascular tube that defines a non-vascular tube diameter and is configured to receive organ system seed cells, and a barrier formed between the vascular tube and the non vascular tube.

A perfusion manifold assembly is described that allows for perfusion of a microfluidic device, such as an organ on a chip microfluidic device comprising cells that mimic cells in an organ in the body, that is detachably linked with said assembly so that fluid enters ports of the microfluidic device from a fluid reservoir, optionally without tubing, at a controllable flow rate.

A culture module is contemplated that allows the perfusion and optionally mechanical actuation of one or more microfluidic devices, such as organ-on-a-chip microfluidic devices comprising cells that mimic at least one function of an organ in the body.
