The pressure and circulation culture apparatus includes a holder (culture chamber part), a pressure transmission part and a culture solution circulation line (culture circuit). The holder is a means that reserves culture solution and that holds a cultured object. The pressure transmission part is a means that communicates with the holder and transmits an external pressure to the culture solution. The culture solution circulation line is a means that is connected to the holder via the pressure transmission part, and circulates the culture solution through the holder via the pressure transmission part. Such a structure is included, and an external pressure is made to operate on the culture solution via the pressure transmission part to allow pressure on the cultured object in the holder and circulation of the culture solution in the holder.

The present invention is directed to a system and method for producing an organic compound using fermentation wherein multiple components of the system are recycled within the system. The system and method allow for extraction of a high concentration of the organic compound from the fermentation broth in a continuous system that allows recycling of the biomass, aqueous fermentation broth and extraction solvents. The system and method are particularly well adapted for producing and extracting ethanol.

A system for incubating one or more cells and/or organotypic cultures for biological investigation, in particular for toxicology assessment, comprising a bio-incubator and a pressure system fluidly connected with the bio-incubator. The pressure system is a cyclic gas pressure system configured for cyclically varying the gas pressure in the bio-incubator between a negative pressure and a positive pressure compared to the atmospheric pressure, so as to reproduce the pressure conditions in lungs of a living mammal. The system is remarkable in that the cyclic gas pressure system comprises a feedthrough with a pipe configured to deviate the air influx from the one or more cells and/or organotypic cultures.

A liquid injection method for injecting a liquid into a culture vessel includes tilting the culture vessel around a horizontal axis at a tilt angle (X) of greater than 0 and 50 or less, wherein adherent cells are adhered to the culture vessel; and injecting the liquid into the culture vessel at a predetermined linear velocity (Y mm/s) via a wall surface of the culture vessel tilted at the tilt angle (X), wherein the tilt angle (X) and the linear velocity (Y) satisfy the following (formula 1): Y5.075X+123 (formula 1).

The invention provides cell culture chambers and methods of use thereof. In certain embodiments, the cell culture chambers and methods provide for an expansion and stimulation of T-cells using autologous antigen-presented cells to provide a therapeutic T-cell product that can mobilize a patient's own immune system in a manner that selectively targets a patient's tumor.

A method displacing a fluid and simultaneously gas enriching a liquid cell culture medium with a gas. The method includes injecting a controlled volume of a gas or gas mixture into a one chamber by using a gas flow controller, the injection taking place through a gas inlet into a volume of liquid. This injection produces bubbling and agitation of the volume of liquid; a build-up of gas or gas mixture due to buoyancy in a hermetic space formed by the volume of liquid and the chamber, and a pressure increase in the chamber until a sufficient controlled pressure is reached of less than or equal to 10 bar. This increase displaces the volume of liquid by a fluid outlet connecting the volume of liquid to the exterior of the chamber. Also provided are a device implementing the method and a cell culture system in a multi-well culture plate.

In one example in accordance with the present disclosure, a fluid ejection die is described. The fluid ejection die includes a fluid feed slot to deliver fluid from a reservoir to an array of nozzles. Each nozzle of the array includes an ejection chamber, an opening, a fluid actuator disposed within the ejection chamber, and a fluid channel between the fluid feed slot and the ejection chamber. The fluid ejection die also includes a fluid cleaning structure to allow live cells in the fluid to pass to the nozzle while capturing other components.

An apparatus for processing cells is disclosed. In one embodiment, a fixed bed reactor is provided for the cells, the fixed bed reactor including a portion movable from a first position corresponding to a packed condition of the fixed bed to a second position corresponding to a depacked condition of the fixed bed. Movement of the partition facilitates harvesting of the cells there from. Related apparatus, kits, methods, and systems are also disclosed.

A cell culture apparatus is provided, including a storage tank including one or a plurality of cell culture units, in which the cell culture unit includes a culture chamber having an inner surface-side space in which a culture solution is stored, a permeable membrane having a first surface to which cells are adherable and a second surface opposite to the first surface, the first surface facing the inner surface-side space, a culture solution storage chamber that stores the culture solution, a culture solution introduction flow path that introduces the culture solution in the culture solution storage chamber to the inner surface-side space, and a culture solution discharge flow path that sends, to the culture solution storage chamber, the culture solution which permeates through the membrane from the inner surface-side space and flows into an outer surface-side space that the second surface of the membrane faces.

A transfection device suitable for delivery of various macrostructures (e.g., mitochondria, bacteria, liposomes) is described and uses mechanical force to thereby induce active endocytosis in a target cell. Contemplated devices are able to achieve high throughput of transfected cells that remain viable and are capable of producing colonies.
