Disclosed is a wet granulated cell culture medium and a preparation method therefor and, more specifically, to a wet granulated cell culture medium which supports the growth of mammalian cells and/or insect cells and/or plant cells and bacteria, and a preparation method therefor.

A method of promoting spheroid formation, including: a preparation step of preparing a mixture obtained by mixing a cell sample with a promoter; and a culture step of culturing, inside a spheroid formation-culture vessel, the mixture obtained in the preparation step, in which the promoter is a polymer in which one or more selected from the group consisting of D-glucosamine, D-galactosamine, D-glucuronic acid, L-iduronic acid, and D-galactose are polymerized.

The present invention relates to fluorescent dyes. The present invention provides a wide range of fluorescent dyes and kits containing the same, which are applicable for labeling a variety of biomolecules, cells and microorganisms. In one aspect, the invention provides a compound having a maximal fluorescence excitation wavelength, wherein the compound has a structure of Formula II: ##STR00001##
wherein Z.sup.− is a counterion, Y is a bridge unit permitting electron delocalization between F and Ψ, and F is a moiety having the structure: ##STR00002## The present invention also provides various methods of using the fluorescent dyes for research and development, forensic identification, environmental studies, diagnosis, prognosis, and/or treatment of disease conditions.

This invention provides a system for efficiently producing differentiated cells from pluripotent cells, such as human embryonic stem cells. Rather than permitting the cells to form embryoid bodies according to established techniques, differentiation is effected directly in monolayer culture on a suitable solid surface. The cells are either plated directly onto a differentiation-promoting surface, or grown initially on the solid surface in the absence of feeder cells and then exchanged into a medium that assists in the differentiation process. The solid surface and the culture medium can be chosen to direct differentiation down a particular pathway, generating a cell population that is remarkably uniform. The methodology is well adapted to bulk production of committed precursor and terminally differentiated cells for use in drug screening or regenerative medicine.

The present invention relates generally to the field of nutrition, health and wellness. In particular the present invention relates to probiotics and ways to increase their effectiveness. One embodiment of the present invention relates to a combination of probiotics with SIgA and possible uses of this combination. For example a use of a composition comprising SIgA and at least one probiotic for the preparation of a product to treat or prevent inflammation is disclosed.

The present invention relates to the production of adeno-associated viral vectors in insect cells. The insect cells therefore comprise a first nucleotide sequence encoding the adeno-associated virus (AAV) capsid proteins, whereby the initiation codon for translation of the AAV VP1 capsid protein is an AUG. Upstream of the VP1 open reading frame an alternative out of frame start codon is placed such that translation initiation of the VP1 protein is modified, i.e. reduced, to allow production of VP1:VP2:VP3 in a good stoichiometry resulting in AAV with high potency.

The present invention relates to a method to modulate the level of activation of an engineered immune cell (such as a Chimeric Antigen Receptor T-cell) for immunotherapy. The present invention also relates to cells obtained by the present method, preferably comprising said modulable/tunable chimeric antigen receptors for use in therapeutic or prophylactic treatment.

The present invention provides a method of peptide histochemical diagnosis to detect the peptide binding protein in the cancer tissue. This peptide binding specifically to tumor cells is linked to the dextran coated iron oxide nanoparticle. The peptide linked dextran coated iron oxide nanoparticle can be used to bind to the formalin-fixed and paraffin-embedded tumor surgical specimens, and the method of present invention can be used to evaluate the efficacy of peptide-targeted chemotherapy for treatment of cancer patients.

Disclosed herein are media for culture of cells, tissues, and/or organs. The media formulations disclosed herein can be used to support growth, viability, and/or function of one or more than one cell type, tissue, or organ. In some embodiments, one or more cell types, tissues, organ devices, and/or organs are contacted with a disclosed culture medium under conditions sufficient to support growth, viability, and/or function of the cell types, tissues, and/or organs. The disclosed media can be used in methods of culturing multiple cell types, and in some examples, is used in a platform device including one or more organ devices, for example, by circulating the medium through the one or more organ devices in the platform.

The present invention relates to systems and devices to treat and/or prevent inflammatory conditions within a subject and to related methods. More particularly, the invention relates to systems, devices, and related methods that sequester leukocytes and/or platelets and then inhibit their inflammatory action.
