  • Patent number: 11613735
    Abstract: A method for inducing reprogramming of a cell of a first type which is not a non-hepatocyte (non-hepatocyte cell), into a cell with functional hepatic drug metabolizing and transporting capabilities, is disclosed. The non-hepatocyte is induced to express or overexpress hepatic fate conversion and maturation factors, cultured in somatic cell culture medium, hepatocyte cell culture medium and hepatocyte maturation medium for a sufficient period of time to convert the non-hepatocyte cell into a cell with hepatocyte-like properties. The iHeps induced according to the methods disclosed herein are functional induced hepatocytes (iHeps) in that they express I and II drug-metabolizing enzymes and phase III drug transporters and show superior drug metabolizing activity compared to iHeps obtained by prior art methods. The iHeps thus provide a cell resource for pharmaceutical applications.

  • Publication number: 20220362387
    Abstract: Senolytic and anti-inflammatory prodrugs are provided, which are designed from a cytotoxic agent, by chemically modifying the cytotoxic agent to incorporate a site cleavable by SA-?-gal following delivery of the prodrug in vivo, to release the active parent drug. The prodrug includes a galactose-based moiety, which is preferably acetylated, and benzyl oxy carboxy group and a cytotoxic agent moiety. The selenolytic prodrug is used to selectively kill one or more senescent cells and/or reduce an acute or chronic inflammatory response in a subject in need thereof, by administering to the subject therapeutically effective amount of the senolytic prodrugs. The disclosed compositions can be used to reduce one or more symptoms associated with a Senescence-associated disease or disorder or an inflammatory disorder, for example, a virus-mediated inflammation, in a subject.

  • Patent number: 11002736
    Abstract: SUSD2 protein is used as a marker in identification, selection or separation of pancreatic internal secretion precursor cells and/or newborn pancreatic internal secretion cells; and a use of an mRNA, for encoding the SUSD2 protein, of a precursor protein as the marker in identification of the pancreatic internal secretion precursor cells and/or the newborn pancreatic internal secretion cells. Analysis of gene expression of pancreatic endoderm cells sourced by induced directional differentiation of human pluripotent stem cells finds the enrichment expression of a SUSD2 gene in the pancreatic internal secretion precursor cells and the newborn pancreatic internal secretion cells. A protein encoded by the SUSD2 gene is a receptor protein on cell membranes. Using the protein as the marker, the identification, the selection or the separation of the pancreatic internal secretion precursor cells and the newborn pancreatic internal secretion cells can be conducted.
