Disclosed herein are milk compositions that comprise protein, lipid, and oligosaccharide components at concentrations that mimic and/or are substantially similar to human breast milk as produced by a lactating female. The milk compositions include one or more milk components produced in vitro and/or ex vivo from cultured mammary cells.

Provided herein are cultured milk products for use as nutritional supplements. Also provided are live cell constructs for producing the cultured milk products and bioreactors for producing the cultured milk products. Secretory IgA compositions and methods of use are also provided.

The present technology relates to three-dimensional biomimetic platforms for culturing patient specific cells and tissues in biological material that closely recapitulates the native in vivo environment. The platforms of the present technology enable rapid and flexible biochemical, genomic, and metabolic analysis using a wide variety of assays, and live or end-point biological imaging.

Disclosed herein are milk compositions that comprise protein, lipid, and oligosaccharide components at concentrations that mimic and/or are substantially similar to human breast milk as produced by a lactating female. The milk compositions include one or more milk components produced in vitro and/or ex vivo from cultured mammary cells.

Devices and systems for cell culture that include one or more hollow fibers or channels integrated into a chamber are provided. The hollow fibers or channels and/or the chamber are seeded with one or more cell types. Methods of co-culturing two or more cell types in the devices are also provided.

The invention relates to methods for culturing antibody secreting cells, and related methods, constructs and compositions.

The present invention relates to therapeutic uses of ex vivo generated Foxp3+ regulatory T cells. The inventors showed the presence of Foxp3+ expressing T cells in tumor infiltrating lymphocytes (TILs) isolated from luminal-B breast cancer. The inventors performed an ex vivo generation and expansion of specific CD3+ TCRy8+ expressing Foxp3: CD3+ TCRy8+ T cells maintain their Foxp3 level and their suppressive activity, after a further 21-day-culture. They also showed that tumor Ag-specific CD3+ TCR Va24+ T cells maintain their ability to perform suppressive function in pro-inflammatory conditions. In particular, the present invention relates to immunotherapeutic uses of at least one of ex vivo generated Foxp3+regulatory T cells population selected among a MHCII restricted CD4+Foxp3+regulatory T cells population, a y8 Foxp3+regulatory T cells population and an invariant Foxp3+regulatory T cells population.

Devices and systems for cell culture that include one or more hollow fibers or channels integrated into a chamber are provided. The hollow fibers or channels and/or the chamber are seeded with one or more cell types. Methods of co-culturing two or more cell types in the devices are also provided.

A normal regenerated tissue is formed by exposing to radiation a connective tissue or a supporting tissue originating in an organ to thereby form a feeder layer and then transplanting epithelial cells thereon to form a stratified structure. By conveniently and surely providing regenerated tissue by the 3-dimensional culture with the use of a human-origin normal tissue as a base, it is possible to construct systems for assessing effects and side effects of chemicals such as drugs or assessing sensitivities thereof with the use of regenerated tissues as models of corresponding tissues respectively.

Described herein are compositions and methods of forming multi-cellular tumoroids. Also described herein are methods of using the multi-cellular tumoroids.
