A polymer compound in which a polymer chain containing a structure contributing to the inclusion of intermediate water is bound as at least a part of the organic component R group of a silsesquioxane.

The present disclosure provides advantageous rotary interfaces for fluid assemblies (e.g., rotary interfaces for fluid flow in bioreactor applications), and related methods of fabrication and use. More particularly, the present disclosure provides improved rotary interfaces for fluid flow through porous impellers for filtration and/or sparging for fluid assemblies (e.g., bioreactor applications), and related methods of fabrication and use. Disclosed herein is a fluid assembly (e.g., bioreactor) that includes a porous impeller which is in fluid communication with a hollow shaft that can be used to transport a reaction fluid to an external storage tank or the like. The fluid assembly/bioreactor can include a coupling mechanism that transmits rotary motion from a motor to a primary shaft and then to a hollow secondary shaft, while at the same time permitting removal of a filtrate from the fluid assembly or bioreactor via the hollow secondary shaft and a porous impeller.

An assembly for delivering a fluid includes a fluid dispenser connected to a fluid supply conduit. The fluid dispenser includes a fluid outlet positioned along a length of the fluid dispenser. The fluid outlet is configured to deliver the fluid from the fluid supply conduit at a flow rate that varies along the length of the fluid dispenser.

A plant fat-based scaffold for growing cell-based meat products for consumption. The scaffold comprises primarily plant fats or waxes in addition to cell binding proteins and optional additional components that assist in the growth of cultivated animal cells. The scaffold can exist in both a liquified state during sterilization and a solid state during the formation of the scaffold, the seeding of the cultivated cells, and the cellular growth phase. The scaffold is capable of remaining in the final product for consumption or is partially or completely melted out of the final product and recycled into raw material for forming new scaffolds.

A cell culture vessel, cell culture monitoring system, and Raman spectroscopy system for non-invasive measuring of a cell culture are provided. The vessel includes a cell culture chamber that operates as a closed system, a wall defining a boundary of the cell culture chamber and separating the interior space of the cell culture chamber from an exterior of the cell culture chamber, and a window disposed in the wall and separating the interior space of the cell culture chamber from an exterior of the cell culture chamber. The cell culture chamber includes an interior space for housing at least one of the cell culture and a cell culture media. The window includes a polymer and allows monitoring of the cell culture via a monitoring module disposed on the exterior without the monitoring module coming into physical contact with the cell culture or the cell culture media.

A cell culture device is provided. A cell culture device according to an exemplary embodiment of the present invention comprises: a housing which has a plurality of through-holes formed through at least one surface thereof to allow carbon dioxide to be introduced thereinto from the outside and includes an inner space filled with a medium for culturing cells; a plurality of supporters which are arranged in the inner space in multiple steps while being spaced at an interval from each other so as to culture cells and are provided in a plate-shape having a predetermined area; and a porous member which is attached to one surface of the housing so as to cover the plurality of through-holes, prevents the medium filled in the inner space from leaking to the outside, and allows carbon dioxide to be introduced into the inner space from the outside.

A cell culture apparatus is provided. A cell culture apparatus according to one exemplary embodiment of the present invention comprises: a cell culture part comprising an accommodation space in which a plurality of supports for cell culture are disposed; a medium supply part for storing a predetermined amount of medium to be supplied to the cell culture part, and maintaining a predetermined carbon dioxide concentration of the medium stored therein by using carbon dioxide introduced from the outside through a gas supply port; and a pump, which interconnects the cell culture part and the medium supply part so as to circulate, in the cell culture part, a medium stored in the medium supply part.

The present invention relates to a multicellular construct that includes cells and a scaffold. The scaffold is constituted by a layered composite that comprises a gelatin nonwoven containing gelatin as a main component, and a gelatin film containing gelatin as a main component and layered on one surface of the gelatin nonwoven, and the cells are present in at least one of a region on the surface of the gelatin nonwoven and a region inside the nonwoven. The multicellular construct can be produced by arranging the scaffold in a swollen state inside the culture vessel whose inner surface is in the dry state such that the gelatin film of the scaffold is in contact with the inner bottom surface of the culture vessel, dripping a cell suspension onto the gelatin nonwoven of the scaffold, and then culturing the cells. This makes it possible to provide a multicellular construct with high seeding efficiency in which desorption of cells from a scaffold is suppressed, a method for manufacturing the same, a kit for producing the same, and a method for evaluating a compound using the same.

A three-dimensional cell growth containment article is described, which includes a molded body channelized by removal of sacrificial channelizing element(s) therefrom, so that the molded body contains one or more channel(s) therein, with a matrix material in at least one of such channel(s) that is supportive of three-dimensional cell growth in the matrix material. A method for making such articles is also described, in which a molded body is formed with one or more sacrificial channelizing element(s) therein, following which the sacrificial channelizing element(s) are removed. The three-dimensional cell growth containment articles of the present disclosure may be utilized in any applications in which there exists a need to reproducibly generate three-dimensional cellular structures, e.g., islet transplantation for diabetes treatment, transplantation of hormone secreting cells, cellular scaffolds for wound healing, and generation of tissue engineering structures to regain structural usefulness for orthopedic applications.
