  • Publication number: 20170355962
    Abstract: 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 ?-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 ?-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 ?-cell.

  • Patent number: 9005382
    Abstract: A method for forming a ceramic matrix composite (CMC) component for gas turbine engines. The method contemplates replacing a plurality of plies with insert material. The insert material can be partially cured or pre-cured and applied in place of a plurality of small plies or it may be inserted into cavities of a component in the form of a paste or a ply. The insert material is isotropic, being formed of a combination of matrix material and chopped fibers, tow, cut plies or combinations thereof. The use of the insert material allows for features such as thin edges (650) with thicknesses of less than about 0.030 inches and small radii such as found in corners (680, 710). The CMC components of the present invention replace small ply inserts cut to size to fit into areas of contour change or thickness change, and replace the small ply inserts with a fabricated single piece discontinuously reinforced composite insert, resulting in fewer defects, such as wrinkles, and better dimensional control.
