  • Patent number: 9234179
    Abstract: The present invention relates to a method of reprogramming a somatic cell to produce an induced pluripotent stem (iPS) cell which is capable of differentiating into somatic cells derived from ectoderm, mesoderm or endoderm. The present invention also relates to the aforementioned iPS cells, methods of generating and maintaining iPS cells, and methods of using iPS cells.
    Type: Grant
    Filed: December 18, 2009
    Date of Patent: January 12, 2016
    Assignees: SHANGHAI ICELL BIOTECHNOLOGY CO., LTD., SHANGHAI UNITED STEM CELL BIOTECHNOLOGY CO., LTD.
    Inventors: Lihe Guo, Tianjin Liu
  • Patent number: 9163214
    Abstract: In the field of biological technology, a stem cell culture method is provided. The method includes preparing an amniotic epithelial cell feeder layer that is not treated to lose the division ability; and seeding the stem cells onto the amniotic epithelial cell feeder layer, and culturing in a culture medium. The stem cell culture method according to the present invention does not require the treatment of the feeder layer cells to lose the division ability, and is thus simple and safe, thereby effectively solving the problem of contamination caused by animal-derived ingredients in culture of human stem cells at present, greatly reducing the culture cost of the stem cells, and providing a safe, effective, and inexpensive stem cell culture method for the industrialization of the stem cells in the future.

  • Patent number: 7779774
    Abstract: A vehicle may utilize a faceplate, such as a non-circular faceplate, as part of an indicating instrument, such as a speedometer, in a dashboard. The speedometer utilizes a laser to direct laser light onto or through indicia, adjacent a numerical scale, of the faceplate. A first motor mounted to a printed circuit board is used to rotate the laser in a first plane, and a second motor is used to rotate the laser in a second plane. The laser may reside in a housing having a slit or slot for the laser light to pass through to illuminate the faceplate indicia. The first motor is mounted between the printed circuit board and the second motor while a connecting post may be utilized between the first and second motors to position the laser closer to the faceplate indicia, depending upon spatial packaging requirements and the laser light of the laser.
