摘要:
The present invention relates to a novel MDCK-derived cell line capable of being suspension-cultured in a protein-free medium and a method for proliferating a virus using the MDCK-derived cell line to produce a vaccine. The novel MDCK-derived cell line exhibits high and uniform productivity for various viruses, while causing less viral antigenic variations with low tumorigenicity, and thus can be useful in producing viruses used for vaccines.

Novel MSC stem-cell culture and therapy methods and culture medium compositions for the purpose of inducing, activating, or priming discrete uniform cell phenotypes to selectively promote or suppress inflammation and immunity, yielding polarized, primed, activated, or induced cells used in cell-based therapy.
摘要:
Provided herein are methods for the in vitro differentiation of induced pluripotent stem cells, which have been expanded and/or maintained under defined conditions, into endodermal precursor cells (EPCs) that are capable of producing mono-hormonal beta cells.
摘要:
The invention pertains to the use of (i) one or more C 2 -C 6 alpha-hydroxy acids, salts of these acids, esters of these acids and combinations thereof; and (ii) one or more compounds selected from -the group of amino acid derivatives consisting of γ-glutamyl amino acids, pyroglutamyl amino acids, glutamate-containing or proline-containing dipeptides, oxo-aminoacids, homo-amino acids, N-acetyl amino-acids and glycyl-glycine; -phenolic acid derivatives; -linear C 2 -C 6 or cyclic C 6 sugar alcohols; -pyridinic acid derivatives; and -nucleobases and/or nucleotides chosen from uracil, adenine,adenosine 3'- monophosphate (3'-AMP) and adenosine 5'-monophosphate (AMP), as a growth-and production promoting ingredient, in culture media for culturing eukaryotic cells. The invention further pertains to culture media containing these componentsat levels of at least 0.001 mg/l.
摘要:
Fully defined media that support pluripotent cell viability, proliferation, cloning, and derivation, as well as methods and compositions including these media are described. Methods for deriving iPS cells from adult individuals under defined, xeno-free conditions are also described.
摘要:
The present invention relates to an animal protein-free cell culture medium, comprising at least one polyamine and at least one protein hydrolysate derived from the group consisting of plants and yeast, wherein the polyamine is present in the culture medium in a concentration ranging from 2 to 8 mg/L and the protein hydrolysate is present in a concentration ranging from 0.05 % (w/v) to about 0.5 % (w/v).
摘要:
A novel cell suited for mass production of Hemagglutinating Virus of Japan (HVJ), a method for obtaining the cell and use of the cell are disclosed. The human cell is originated from a transformed human kidney cell line, the doubling time thereof in logarithmic growth phase in suspension culture in a serum-free medium is not more than 40 hours, the cell has a freeze-recovery property, the maximum density of viable cells in suspension culture is not less than 10 6 cells/mL, and HVJ can grow in the cell. The method for obtaining the human cell comprises the steps of suspension-culturing a human transformed kidney cell line in a serum-free medium, and cloning the grown cells; and selecting, from the cloned cells, a cell whose doubling time in logarithmic growth phase in suspension culture in a serum-free medium is not more than 40 hours, which has a freeze-recovery property, whose maximum density of viable cells in suspension culture is not less than 10 6 cells/mL, in which HVJ can grow.
摘要:
The invention relates to preparing and/or supplementing a cell or tissue culture medium. In particular, said invention relates to a serum-free and/or protein-free cell culture medium comprising peptide fractions isolated from rapeseeds, in particular rapeseeds cakes. A method for the production of a cell culture comprising said peptide fractions and for the use thereof is also disclosed.
摘要:
Attempts have been made to develop host cells capable of producing glycoprotein compositions such as antibody compositions useful in drug discovery. It is intended to provide a cell having been neutralized to a serum-free medium and carrying a knockout genome gene of an enzyme which participates in a sugar chain modification whereby fucose is attached via an alpha-bond at the 1-position to the 6-position of N-acetylglucosamine at the reducing end of an N-glycoside-binding complex sugar chain; and a process for producing a glycoprotein composition with the use of this cell.
