20080261879 | Method of inducing and maintaining neuronal cells - The present invention makes available a method for inducing neuronal differentiation and preventing the death or degeneration of neuronal cells both in vitro and in vivo. The subject method stems from the unexpected finding that, contrary to traditional understanding of neural induction, the default fate of ectodermal tissue is neuronal rather than mesodermal and/or epidermal. In particular, it has been discovered that preventing or antagonizing a signaling pathway in a cell for a growth factor of the TGF-β family can result in neuronal differentiation of that cell. | 10-23-2008 |
20110014164 | EFFICIENT INDUCTION OF PLURIPOTENT STEM CELLS USING SMALL MOLECULE COMPOUNDS - The disclosure features a method of producing an induced pluripotent stem cell a somatic cell. The method includes contacting a somatic cell with a DNA methyl transferase inhibitor or a histone deacetylase (HDAC) inhibitor, or a combination thereof, to produce a pluripotent stem cell. | 01-20-2011 |
20110070645 | COMPOSITIONS AND METHODS FOR PROMOTING THE GENERATION OF PDX1+ PANCREATIC CELLS - Certain embodiments disclosed herein are directed to a method of producing pancreatic cells or pancreatic cell precursors by exposing human embryonic stem cells to an effective amount of at least one compound listed in Table I to differentiate the human embryonic stem cells into the pancreatic cells or the pancreatic cell precursors. Kits and pancreatic cell lines produced using the methods are also described. | 03-24-2011 |
20110280842 | METHODS OF REPROGRAMMING CELLS - The present invention provides methods of reprogramming cells, for example, directly reprogramming a somatic cell of a first cell type into a somatic cell of a second cell type, are described herein. In particular, the present invention generally relates to methods for reprogramming a cell of an endoderm origin to a cell having pancreatic β-cell characteristics. The present invention also relates to an isolated population comprising reprogrammed cells, compositions and their use in the treatment of diabetes mellitus. In particular, the present invention relates to reprogramming a cell of an endoderm origin to a cell having pancreatic β-cell characteristics by increasing the protein expression of at least one transcription factor selected from Pdx1, Ngn3 or MafA in the cell of endoderm origin to reprogram the cell of an endoderm cell to a cell which exhibits at least one or at least two characteristics of an endogenous pancreatic β-cell. | 11-17-2011 |
20120088300 | COMPOSITIONS AND METHODS FOR PROMOTING THE GENERATION OF DEFINITIVE ENDODERM - 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. Differentated 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. Kits and compositions comprising Pdx1-positive pancreatic progenitor produced using the methods are also described. | 04-12-2012 |
20130023491 | BETA-CELL REPLICATION PROMOTING COMPOUNDS AND METHODS OF THEIR USE - In the invention provides for a method of stimulating or increasing β-cell replication or growth, by contacting a β-cell with an inhibitor of adenosine kinase (ADK), an inhibitor of S-Adenosylhomocysteine hydrolase (SAHH) or an activator of AMP activated protein kinase (AMPK). | 01-24-2013 |
20140024114 | COMPOSITIONS AND METHODS FOR PROMOTING THE GENERATION OF DEFINITIVE ENDODERM - 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. Kits and compositions comprising Pdx1-positive pancreatic progenitor produced using the methods are also described. | 01-23-2014 |
20140287944 | MARKERS FOR FUNCTIONALLY MATURE BETA-CELLS AND METHODS OF USING THE SAME - Markers for functionally mature β-cells and methods of using these markers are disclosed. | 09-25-2014 |
20140303078 | MODULATION OF PANCREATIC BETA CELL PROLIFERATION - Work described herein provides, in one embodiment, a method for increasing proliferation or replication of pancreatic beta cells in a subject in need thereof, comprising administering to said subject an effective amount of an agent that increases the level or activity of hepatocellular carcinoma-associated protein TD26 (TD26), thereby increasing proliferation or replication of pancreatic beta cells. Such an agent may function by, for example, increasing the level of active TD26 in the subject or by increasing the functional activity of TD26 in the subject. | 10-09-2014 |
