Provided are methods of controlling disassociation of cells from a carrier, compositions, and methods of collecting cells. The methods of controlling disassociation of cells from a carrier may include contacting a polymeric carrier with one or more digesting agents to disassociate at least a portion of a plurality of cells from the polymeric carrier. The polymeric carrier may be crosslinked with a crosslinker including at least one of a redox sensitive moiety, a UV light sensitive moiety, a pH sensitive moiety, and a temperature sensitive moiety.

Disclosed herein are methods of making a mold for use with cells, such as engineered tissue. The method includes printing a 3D printed resin mold, casting a hydrogel over the 3D printed resin mold to create a crosslinked hydrogel negative mold, and casting a silicone rubber elastomer over the hydrogel negative mold to create a master mold.

Disclosed are an electrically conductive hydrogel having a graphene network and a method for fabricating the same. The electrically conductive hydrogel is fabricated by thermal annealing of granular hydrogel, and thus it has a porous structure, excellent electrical conductivity, and improved compressive modulus and yield stress. Accordingly, the electrically conductive hydrogel may be advantageously used in biomedical applications, such as scaffolds for tissue engineering, bioelectrodes, and biosensors.

The present application relates to a multi-layer film comprising a nutrient material for cell culture, a method for preparing same, and the use of same. The multi-layer film of the present application can be utilized for cell culture for preparing cultured meat.

The present invention provides a method to quantitatively measure the response of a patient to an immune-modulator drug that will aid clinicians in the determination of the optimal combination/posology of immunosuppressant/immune-modulator drugs. In addition, this method will open the possibility for clinicians to make the necessary adjustments in immunosuppressive therapy, as a way to avoid organ rejection to actually take place. Furthermore, this method will significantly reduce side effects of immunosuppressant drugs, optimizing therapeutic scheme and dosages, enabling the determination of the most effective immunosuppression regimen at the lower dosages for each patient individually and monitoring of treatment efficiency along time, thus opening the door to treatment personalization.

Provided herein are methods for the preparation of perfusable scaffolds for cell culture. These methods can comprise providing a bioink composition and a fugitive ink composition; chaotic printing the bioink composition and the fugitive ink composition to generate a microstructured precursor comprising a plurality of lamellar structures formed from the bioink composition; curing the bioink composition to form a cured scaffold precursor; and removing the fugitive ink from the cured scaffold precursor, thereby forming the perfusable scaffold. Also provided are scaffolds prepared by these methods as well as modular bioreactors incorporating these scaffolds.

The present invention discloses an extracellular matrix comprising a modified polysaccharide consisting of repeating disaccharide units whereby in at least 11% of the disaccharide units one primary alcohol group is oxidized into a carboxylic acid.

A structure for culturing cells includes growth medium regions on a surface of the structure. Each of the growth medium regions includes a growth medium surface configured to receive and promote growth in a cell that is being cultured. The structure includes a non-growth medium. The non-growth medium includes a non-growth medium surface configured to receive the cell that is being cultured.

Provided are an organoid having a metastatic property when transplanted into an immunocompetent non-human animal of the same species, a cell strain having a metastatic property when transplanted into an immunocompetent non-human animal of the same species, and a non-human animal including the organoid or the cell strain.

The present disclosure relates to agarose and methylcellulose storage and transport mediums, systems for cell storage and transport, and cell storage and transport methods. The instantly-disclosed agarose and methylcellulose storage and transport medium is ideally suited for 3D spheroid cell culture storage and transport. In particular aspects, the storage and transport mediums, systems, and methods are used in combination with or performed in labware that combine 3D spheroid culture with a gas permeable, micro-patterned design that allows for protection and prolonged maintenance of spheroid cell (e.g. hepatocytes) viability and functionality during storage and transport.
