This disclosure relates to populations and compositions of purified cell-derived vesicles and uses thereof. One aspect of the disclosure relates to methods for purifying the cell-derived vesicles.

An aqueous cell culture medium composition includes an aqueous cell culture solution configured to support the culture of mammalian cells. The composition further includes a synthetic polymer conjugated to a polypeptide dissolved in the aqueous cell culture solution. The synthetic polymer conjugated to a polypeptide is configured to attach to the surface of a cell culture article under cell culture conditions. Incubation of the aqueous cell culture medium composition on a cell culture surface under cell culture conditions results is attachment to the surface of the synthetic polymer conjugated to the polypeptide.

The present invention relates to methods of modulating the mannose content of recombinant proteins.

The present invention is of methods of establishing and propagating human embryonic stem cell lines using feeder cells-free, xeno-free culture systems and stem cells which are capable of being maintained in an undifferentiated, pluripotent and proliferative state in culture which is free of xeno contaminants and feeder cells.

The invention provides stable feed media containing pyruvate and methods for stabilizing feed media by adding pyruvate. The invention further provides methods for producing proteins using such media and proteins produced through the use of such methods.

A technology regarding the production, formulation and use of conditioned media and the factors included therein is disclosed. The conditioned media may be inoculated with animal cells, plant cells and any combination thereof. The inoculations may occur simultaneous or at different times. Cells retrieved from different areas of the animal and/or the plant may also be cultured together to form conditioned media and associated growth factors.

The present invention relates to dry cell culture media comprising amino acid components of certain particle size. Some dry powder cell culture media show poor dissolving properties and result in turbid solutions when they are dissolved in aqueous solutions. Using amino acid components of certain particle sizes significantly reduces that problem.

Provided are methods of making innate immune cell compositions containing gamma.delta () T cells and/or Natural Killer (NK) cells, and the resulting compositions and related products of manufacture and kits for use in cancer and infectious disease therapy. The methods provided herein permit tailoring of the relative amounts of gamma.delta () T cells and Natural Killer (NK) cells in the compositions, for cellular therapies against a wide variety of cancers and infectious diseases. The resulting compositions can further be used to generate compositions containing either NK cells alone or gamma.delta T cells alone, for immune cellular therapies. The compositions provided herein also can be genetically altered: the gamma delta T cells and Natural Killer cells are modified to express chimeric antigen receptors (CARS) or exogenous T cell receptors (TCRs), which can be used to target any cell surface molecule either directly or indirectly, e.g., a marker on a cancer cell or an infected cell.

Disclosed herein is a cell culture media containing L-glutamine from a set of N-acylated dipeptides Acyl-X-Q, and L-glutamine from a set of other glutamine-sources Qsource in a defined molar ratio R=n(Acyl-X-Q)/n(Qsource), wherein the variables X, Q, Acyl, R, n(Acyl-X-Q) and n(Qsource) are defined in the general disclosure. Processes of using the cell culture media are also described herein.

A serum-free and animal-component-free culture media for expansion of muscle satellite cells is disclosed. The disclosed media can be for use in cultured food applications. The disclosed media can include a baseline serum-free and animal component-free culture media and a recombinant version of albumin. The baseline media, in use, provides a baseline growth capability for expansion of the muscle satellite cells for use in cultured food applications. The disclosed media, in use, provides an improved growth capability for expansion of the muscle satellite cells. The improved growth capability is at least 50% greater than the baseline growth capability. Methods of making and using the disclosed media are also disclosed.
