Method for producing double-stranded RNA-rich lactic acid bacterium, and said lactic acid bacterium
An object of the present invention is to provide a method for efficiently obtaining a lactic acid bacterium that is made to contain a large amount of double-stranded RNA; and a lactic acid bacterium having a high double-stranded RNA content obtained by the method. The object is achieved by: (1) a method for producing a double-stranded RNA-containing lactic acid bacterium, including a step of culturing a lactic acid bacterium under at least one condition of an aeration condition and a low-temperature condition lower than an optimum temperature, thereby obtaining the double-stranded RNA-containing lactic acid bacterium; (2) a double-stranded RNA-containing lactic acid bacterium, in which the content of double-stranded RNA is 2.0 times or more as compared with the content of double-stranded RNA when a bacterium of the same strain is cultured for the same culture time under an optimum temperature and non-aeration condition; or the like.
Methods of manufacture of immunocompatible amniotic membrane products
Provided herein is a placental product comprising an immunocompatible amniotic membrane. Such placental products can be cryopreserved and contain viable therapeutic cells after thawing. The placental product of the present invention is useful in treating a patient with a tissue injury (e.g. wound or burn) by applying the placental product to the injury. Similar application is useful with ligament and tendon repair and for engraftment procedures such as bone engraftment.
Methods of manufacture of therapeutic products comprising vitalized placental dispersions
This invention provides a fluid therapeutic placental product comprising placental cells and a placental dispersion comprising placental factors. The placental cells and the placental dispersion are derived from placental tissue. A placental tissue can optionally be an amnion, chorion, or a trophoblast-depleted chorion. The placental product of the present invention is useful in treating a patient with a tissue injury (e.g. wound or burn) by applying the placental product to the injury. Similar application is useful with ligament and tendon repair and for engraftment procedures such as bone engraftment.
Methods of preparing a primary cell sample
The invention provides methods of preparing a sample of viable diseased cells obtained from a human subject for clinical testing, wherein the methods inhibit anoikis and/or anoikis in the cells while maintaining the physiological functions and genomic composition of the cells when they were in vivo. In the methods of the invention, primary cells are cultured in media comprising at least one anoikis inhibitor, preferably at least one inhibitor of an intrinsic anoikis pathway and at least one inhibitor of an extrinsic anoikis pathway, under anti-anoikis atmospheric conditions, such as greater than 2% and less than 20% oxygen. Method combining multiple culturing conditions, including surface attachment under conditions that inhibit anoikis, are also provided. Compositions and kits for use in the methods of the invention are also provided.
Cell culture medium
The present invention provides a basal cell culture medium and a feed medium with novel amino acid ratios and/or iron choline citrate as iron carrier that result in improved performance of mammalian cell culture processes, such as CHO cultivation and protein production processes, in particular in increased product titer (e.g. of monoclonal antibodies). Also provided are methods for culturing mammalian cells and producing a protein of interest using said basal cell culture medium and optionally feed medium. The invention also provides for a medium platform that comprises (i) the basal cell culture medium and (ii) the feed medium.
Cell culture methods and devices utilizing gas permeable materials
Gas permeable devices and methods are disclosed for cell culture, including cell culture devices and methods that contain medium at heights, and certain gas permeable surface area to medium volume ratios. These devices and methods allow improvements in cell culture efficiency and scale up efficiency.
ASSESSING RETINAL PIGMENT EPITHELIAL CELL POPULATIONS
A method of qualifying whether a cell population is a suitable therapeutic for treating an eye condition is disclosed. The method comprises analyzing co-expression of premelanosome protein (PMEL17) and at least one polypeptide selected from the group consisting of cellular retinaldehyde binding protein (CRALBP), lecithin retinol acyltransferase (LRAT) and sex determining region Y-box 9 (SOX 9) in the population of cells.
PRODUCTION METHOD FOR CEREBRAL ORGANOID
A production method for a cerebral organoid having amyloid plaques is provided, the method including a step (a) of forming, in the presence of a SMAD inhibitor, an embryoid body from a pluripotent stem cell having a mutation in an Alzheimer's disease-related gene; a step (b) of embedding the embryoid body after the step (a) in an extracellular matrix and three-dimensionally culturing the embedded embryoid body in the presence of a SMAD inhibitor and a glycogen synthase kinase 3β (GSK3β) inhibitor to form an organoid; and a step (c) of removing the organoid after the step (b) from the extracellular matrix and subjecting the removed organoid to stirring culture in a medium, where at least a part of the step (c) is carried out in the presence of leukemia inhibitory factor (LIF).
METHODS FOR ENRICHING MARROW INFILTRATING LYMPHOCYTES ("MILS"), COMPOSITIONS CONTAINING ENRICHED MILS, AND METHODS OF USING ENRICHED MILS
A method for enriching or isolating tumor specific MILs is described. This method includes the steps of preparing MILs from the bone marrow of a cancer patient; evaluating the MILs for gene expression, metabolic profile, or phenotype; and selecting and isolating the MILs that exhibit the gene expression, metabolic profile, or phenotype. Compositions containing the MILs and methods of treating cancer with the enriched MILs are also described.
SYSTEM FOR PRODUCITON OF HIGH YIELD OF RECOMBINANT PROTEINS
The presently disclosure relates to a system and method for bioelectronic communications. In certain embodiments the system comprises a bacterial cell or cells that comprise a genetic system for high-efficiency over-expression and secretion of recombinant proteins in bacteria. In certain embodiments, the system and method operate in a “pump-then-burst release” fashion to rapidly achieve high yields extracellularly. In certain embodiments, the system and method include quorum sensing-derived regulation, which may enable auto-induction of a protein's expression and secretion.
