  • Publication number: 20240018486
    Abstract: The present invention provides compositions and methods for reprogramming somatic cells using purified RNA preparations comprising single-strand mRNA encoding an iPS cell induction factor. The purified RNA preparations are preferably substantially free of RNA contaminant molecules that: i) would activate an immune response in the somatic cells, ii) would decrease expression of the single-stranded mRNA in the somatic cells, and/or iii) active RNA sensors in the somatic cells. In certain embodiments, the purified RNA preparations are substantially free of partial mRNAs, double-stranded RNAs, un-capped RNA molecules, and/or single-stranded run-on mRNAs.

  • Publication number: 20220257795
    Abstract: The present invention relates to compositions, kits and methods for making and using RNA compositions comprising in vitro-synthesized ssRNA inducing a biological or biochemical effect in a mammalian cell or organism into which the RNA composition is repeatedly or continuously introduced. In certain embodiments, the invention provides compositions and methods for changing the state of differentiation or phenotype of a human or other vertebrate cell. For example, the present invention provides mRNA and methods for reprogramming cells that exhibit a first differentiated state or phenotype to cells that exhibit a second differentiated state or phenotype, such as to reprogram human somatic cells to pluripotent stem cells.

  • Publication number: 20220042007
    Abstract: The present invention provides methods, compositions and kits for using a transposase and a transposon end for generating extensive fragmentation and 5?-tagging of double-stranded target DNA in vitro, then using a DNA polymerase for generating 5?- and 3?-tagged single-stranded DNA fragments without performing a PCR amplification reaction, wherein the first tag on the 5?-ends exhibits the sequence of the transferred transposon end and optionally, an additional arbitrary sequence, and the second tag on the 3?-ends exhibits a different sequence from the sequence exhibited by the first tag. The method is useful for generating 5?- and 3?-tagged DNA fragments for use in a variety of processes, including processes for metagenomic analysis of DNA in environmental samples, copy number variation (CNV) analysis of DNA, and comparative genomic sequencing (CGS), including massively parallel DNA sequencing (so-called “next generation sequencing”).

  • Publication number: 20210079346
    Abstract: The present invention provides methods, kits, and compositions for reducing an innate immune system response in a human or animal cell, tissue or organism. One embodiment comprises: introducing an Agent mRNA comprising in vitro-synthesized mRNA encoding one or more proteins that affect the induction, activity or response of an innate immune response pathway; whereby, the innate immune response in the cell, tissue or organism is reduced compared to the innate immune response in the absence of the Agent mRNA. Other embodiments are methods, compositions and kits for using an Agent mRNA for treating a disease or medical condition in a human or animal that exhibits symptoms of an elevated innate immune system, or for reducing an innate immune response that is induced in a human or animal cell, tissue or organism by a Foreign Substance that is administered to the cell, tissue or organism.
