Method Of Altering The Differentiation State Of The Cell Patents (Class 435/377)
  • Patent number: 8951795
    Abstract: The present invention relates to a method of safely and simply inducing differentiation of mononuclear cells into cells that promote neovascular stabilization and maturation, and lead to recovering from ischemia or tissue repair. The cells according to the present invention are obtained by inducing differentiation of a mononuclear cell by culturing the mononuclear cell in a medium (particularly a serum-free medium) containing one or more selected from vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), thrombopoietin (TPO), granulocyte-colony stimulating factor (G-CSF) and FMS-like tyrosine kinase 3 ligand (FLT3L), and collecting a cell population expressing CD11b.

  • Patent number: 8951798
    Abstract: Methods for generating high-yield, high-purity cardiomyocyte progenitors or cardiomyocytes from pluripotent cells are described. Wnt/?-catenin signaling is first activated in pluripotent cells, e.g., by inhibition of Gsk-3 to obtain a first population of cells. Wnt/?-catenin signaling is then inhibited in the first cell population to induce cardiogenesis under fully defined, growth factor free culture conditions.

  • Patent number: 8945923
    Abstract: The present invention provides recombinant proteins comprising the amino acid sequence of an intracellular segment of CD40 and an amino acid sequence mediating the association of the recombinant protein with the constant region of an immunoglobulin heavy chain. The recombinant proteins according to the present invention are useful for inducing clonal expansion of a B cell having a predetermined antigen-specificity without the need for T cell or CD40L mediated co-stimulation. Thus, the present invention provides tools for clonal expansion of B cells specific for an antigen of interest and the production of B cells secreting antibodies specific for an antigen of interest. The recombinant proteins of the present invention may also be used for generating fully human monoclonal antibodies with a predetermined antigen-specificity from the B cell repertoire of a human subject.

  • Publication number: 20150031129
    Abstract: The present invention relates to stem cells in which a gene that activates signaling is introduced and to a method for proliferating the stem cells. More specifically, the invention relates to a method of significantly increasing the ability of stem cells to proliferate, either by transfecting stem cells with the Notch intracellular domain (NICD) to activate the Notch signaling pathway, or by transfecting stem cells with the c-MET gene and treating the transfected stem cells with the HGF ligand protein to activate the c-MET/HGF signaling pathway. According to the present invention, as a result of activating the Notch signaling pathway or the c-MET/HGF signaling pathway, stem cells having an excellent ability to proliferate can be produced in large amounts. Particularly, since neural stem cells which have been difficult to culture in vitro can be proliferated in large amounts, thus the neural stem cells will be more useful for the preparation of cell therapeutic agents for treating cranial nerve diseases.

    Abstract: The present invention relates to the ex vivo differentiation of NK cells from CD34+ hematopoietic stem cells. Such NK cells and their progenitor cells can be used in therapies of a broad range of malignancies. In the present invention it is shown that IL-12 modulates ex vivo NK cell differentiation. Specific, we achieved significantly higher expression of KIR, CD16 and CD62L in the presence of IL-12 in the cell culture system. The induction of receptor expression by IL-12 occurred predominantly on an augmented population of CD33+NKG2A+ NK cells early during NK cell differentiation. These cells further show enhanced cytolytic activity against MHC class I positive AML targets. In line with the enhanced CD16 expression, IL-12 modulated ex vivo generated NK cells exhibit an improved antibody-dependent-cytotoxicity, using anti CD20 antibody on various B cell targets. Additional to the enhanced expression of CD62L, we show that this cell population consists of a specific chemokine receptor profile.

  • Patent number: 8927278
    Abstract: The present invention develops a straightforward and rapid method for generating immunomodulatory cells from peripheral mononuclear cells, comprising treating peripheral mononuclear cells with a hepatocyte growth factor (HGF) to induce differentiation of the peripheral mononuclear cells into immunomodulatory leukocytes. The present invention also provides an immunomodulatory cell prepared according to this method. The present invention further provides a method for treating a disease caused by abnormal immune response comprising administering a HGF to a patient exhibiting the disease, inducing the patient's peripheral mononuclear cells to differentiate into immunomodulatory leukocytes, and modulating the abnormal immune response.

  • Patent number: 8927280
    Abstract: Certain embodiments disclosed herein are directed to a method of producing endoderm cells, such as definitive endoderm cells by exposing stem cells such as embryonic stem cells or induced pluripotent stem (iPS) cells to an effective amount of at least one compound described herein to differentiate the stem cells into the endoderm cells such as definitive endoderm cells. Differentiated endoderm cells produced by the methods disclosed herein can be differentiated into pancreatic epithelium, and other endoderm derivatives such as thymus, liver, stomach, intestine and lung. Another aspect of the present invention relates to a method of producing pancreatic progenitor cells, such as Pdx1-positive pancreatic progenitor cells by exposing endoderm cells, such as definitive endoderm cells to an effective amount of at least one compound described herein to differentiate the definitive endoderm cells into Pdx1-positive pancreatic progenitor cells.

  • Patent number: 8927274
    Abstract: A method of generating pancreatic progenitor cells is disclosed. The method comprises: (a) differentiating stem cells under conditions such that at least a portion of the cells express glucose transporter 2 (GLUT2) so as to generate GLUT2-expressing cells; and (b) enriching for the GLUT2-expressing cells so as to generate a population of GLUT2 enriched cells, wherein at least 80% of the population of GLUT2 enriched cells express GLUT2, thereby generating pancreatic progenitor cells. Isolated populations of cells generated according to the method, pharmaceutical compositions comprising same and uses thereof are also disclosed.

  • Publication number: 20150004612
    Abstract: A method of generating an induced progenitor population (iPP) of cells and/or induced population of cells from somatic cells, comprising the steps: a) obtaining a starting cell population, wherein cells of the starting cell population comprise, or are contacted with, a nucleic acid molecule encoding four reprogramming factors under the control of a control element, wherein the four reprogramming factors are optionally Oct4, Klf4, Sox2 and c-Myc, and wherein the control element prevents or stops expression of the reprogramming factors under its control in the absence of induction by an inducing agent; and b) transiently inducing expression of the reprogramming factors in the starting cell population to obtain an iPP, c) optionally isolating the iPP, and d) terminating the transient induction while the proliferative capacity of the iPP remains under the control of the one or more exogenous reprogramming factors to produce an induced population of cells.
