A production method comprising the step of forming an aggregate of cells under conditions that permit transfection of the cells with a substance in a non-cell-adhesive container is provided as a technique for producing cells having the desired substance introduced therein on a large scale at a commercial level.

Described herein are methods and compositions for use in expanding alveolar epithelial cells. The methods may include the use of three-dimensional substrates and improved techniques for expansion of the cells. The improved composition for culturing alveolar epithelial cells may include at least one or more of the following: a TGF- pathway inhibitor; a Wnt pathway activator; a ROCK inhibitor; an epidermal growth factor (EGF); a keratinocyte growth factor (KGF); and a fetal bovine serum.

The present application provides non-naturally occurring 3D brown adipose-derived stem cell (BADSC) aggregates, methods of making the 3D BADSC aggregates, and methods of using the 3D BADSC aggregates.

The present disclosure relates to a method for arranging cellular material in a bioink, gel or hydrogel material used in 3D-bioprinting. The method comprises bioprinting or dispensing at least one layer of bioink/gel/hydrogel, dispensing or patterning cellular material in the form of single cells, spheroids or cell suspension on or in the bioink/gel/hydrogel layer using a microfluidic device, and repeating previous steps in order to create a 3D tissue model with multiple cell layers. The present disclosure also relates to corresponding microfluidic devices, computer programs and 3D bioprinters.

An immortalized sweat gland myoepithelial cell which expresses -SMA and pan-cytokeratin and has a sphere forming ability after subculture at least 5 times. A method for producing immortalized sweat gland myoepithelial said method comprising: while culturing a cell structure, wherein sweat gland myoepithelial cells are exposed on a surface, in a state of being suspended in a medium, transferring an immortalizing gene into the cells; and then culturing the transgenic structure thus obtained in a state of being suspended in the medium to thereby obtain immortalized sweat gland myoepithelial cells.

The present invention is directed to the use of microfluidics in the preparation of cells and compositions for therapeutic uses.

A method of making a cell culture article is provided. The method includes forming a microcarrier from a microcarrier composition comprising a polygalacturonic acid compound or an alginic acid compound, infiltrating the microcarrier with a drying formulation to form an infiltrated microcarrier, and drying the infiltrated microcarrier to form a dried microcarrier, wherein the drying formulation comprises at least one of a saccharide and a monovalent cation.

The bioink disclosed herein includes one or more cells, a carrier material, and microspheres. The microspheres can include one or more biodegradable polymers and one or more compounds, such as a morphogenic compound. The methods disclosed herein can include three-dimensional bioprinting. Additional methods disclosed herein include producing functional tissue.

The present invention is directed to the use of microfluidics in the preparation of cells and compositions for therapeutic uses.

The present invention provides an efficient process for culturing viruses in the presence of an endonuclease and for producing vaccines, typically from live attenuated viruses, under conditions to reduce the presence of host cell DNA and eliminate the need for a post-harvest DNA digestion step.
