CONTINUOUS AUTOMATED PERFUSION CULTURE ANALYSIS SYSTEM (CAPCAS) AND APPLICATIONS OF SAME
A continuous automated perfusion culture analysis system (CAPCAS) comprises one or more fluidic systems configured to operate large numbers of biodevices in parallel. Each fluidic system comprises an input reservoir plate for receiving media; a biodevice plate comprising an array of biodevices fluidically coupled to the input reservoir plate, configured such that each biodevice has independent media delivery, fluid removal, stirring, and gas control, and each biodevice is capable of continuously receiving the media from the input reservoir plate; and an output plate fluidically coupled to the biodevice plate for real-time analysis and sampling. The operations of the CAPCAS are automated and computer-controlled wirelessly. The CAPCAS can also be used for abiotic and biotic chemical synthesis processes.
3D CELL CULTURE VESSELS FOR MANUAL OR AUTOMATIC MEDIA EXCHANGE
A cell culture vessel includes a base defining a base plane extending in a first direction and a second direction perpendicular to the first direction, a plurality of cell culture chambers stacked one atop another, each cell culture chamber having a top, a bottom and sidewalls, each of the top, bottom and sidewalls having an interior surface, wherein at least the bottom surface has an array of microcavities supporting the culture of cells as spheroids and each bottom surface is at an angle with respect to the plane of a table or surface upon which the vessel sits. Further, liquid can flow into each cell culture chamber via an inlet and out of each cell culture chamber via an outlet. The angled cell culture surface allows the cell culture chambers to be perfused or allows media changes without dislodging spheroids from microcavities.
CELL CULTURE ASSEMBLIES AND METHODS OF USING THE SAME
A cell culture assembly includes a film defining a plurality of wells extending into the film, where each well of the plurality of wells defines a perimeter extending around the well, the plurality of wells defines an outer perimeter extending around the plurality of wells and extending between the perimeters of adjacent wells of the plurality of wells, and the outer perimeter extending around the plurality of wells defines a wave shape, and a sidewall member coupled to the film, where at least a portion of the sidewall member is oriented transverse to the film, the sidewall member including an engagement portion defining a wave shape that is complementary with the outer perimeter of the plurality of wells.

Highly efficient gas permeable devices and methods for culturing cells
This invention relates to methods and devices that improve cell culture efficiency. They include the use of gas permeable culture compartments that reduce the use of space while maintaining uniform culture conditions, and are more suitable for automated liquid handling. They include the integration of gas permeable materials into the traditional multiple shelf format to resolve the problem of non-uniform culture conditions. They include culture devices that use surfaces comprised of gas permeable, plasma charged silicone and can integrate traditional attachment surfaces, such as those comprised of traditional tissue culture treated polystyrene. They include culture devices that integrate gas permeable, liquid permeable membranes. A variety of benefits accrue, including more optimal culture conditions during scale up and more efficient use of inventory space, incubator space, and disposal space. Furthermore, labor and contamination risk are reduced.
Cell culture vessel, support jig for cell culture vessel and cell culture method
A cell culture container includes a container main body comprising a gas-permeable plastic film, and an injection/discharge port. A peripheral portion of the container main body is sealed, and the container main body has a bulging shape on a top surface side of the container main body. A plurality of concave portions serving as cell culture parts are provided on a bottom surface of the container main body.
POLYMERIC CELL CULTURING SURFACE HAVING HIGH CELL ADHESION
A polymeric substrate has a plasma treated contact surface which is roughened, hydrophilic and has a higher oxygen atomic content than the interior portion. The treated contact surface has an enhanced cell adhesion, cell growth and cell recovery rate. During the treatment, the contact surface is contacted with a process gas introduced through a gas inlet near the treated surface and radio frequency electrical power is introduced in the process gas, forming a treated contact surface that has improved cell recovery compared to an untreated contact surface. The process gas optionally can be nitrogen gas, oxygen gas, or a gas that contains nitrogen atoms, oxygen atoms, or a combination of nitrogen and oxygen atoms. The process optionally improves cell recovery of a chicken embryo cell culture from the treated contact surface.
Bioprocessing vessel
A bioreactor vessel includes a bottom plate, a vessel body coupled to the bottom plate, the vessel body and the bottom plate defining an interior compartment therebetween, and a plurality of recesses formed in the bottom plate, each recess of the plurality of recesses being configured to receive a corresponding alignment pin on a bed plate for aligning the bioreactor vessel on the bed plate.
POLYLACTIDE CELL CULTURE CONTAINERS AND USE IN CELL CULTURE
2D and 3D cell culture containers formed from blends of poly-L-lactide and poly-D-lactide provide growth surfaces for adherent cells and do not require surface treatment or coating to support mammalian cell growth. The cell culture containers are transparent, heat tolerant, and are environmentally degradable and suitable for composting in landfills.
CULTURE MANAGEMENT APPARATUS, ESTIMATION METHOD, AND COMPUTER-READABLE MEDIUM
A culture management apparatus includes a control device that estimates a state of a specific medium component constituting a culture medium based on images including both the culture medium and a cell in the culture medium acquired by an imaging device at different times.
