Patents by Inventor Kuang Ning Chang

Kuang Ning Chang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Human embryonic stem cells and culturing methods thereof
    Patent number: 7682826
    Abstract: Provided herein are human embryonic stem cells and their method of culturing. In one embodiment, the human embryonic stem cells are maintained in an environment containing an extracellular matrix isolated from feeder cells and a conditioned medium pre-conditioned by the feeder cells; the feeder cells are pre-inactivated by either gamma ray radiation or by mitomycin C treatment. The cultured human embryonic stem cells remain substantially undifferentiated and maintain their pluripotency to differentiate into three germ layer cells.
    Type: Grant
    Filed: September 23, 2005
    Date of Patent: March 23, 2010
    Assignee: Industrial Technology Research Institute
    Inventors: Mei Ju Yang, Kuang Ning Chang, Lih Tao Hsu, Jun Jae Huang, Wann Hsin Chen, Chao Ying Kuo
  • Dissecting device
    Patent number: 7255705
    Abstract: A device for dissecting an object, such as a cell colony includes a handle and an incision knife module that can dissociate the colony into several colony pieces. In accordance with features of the invention, users can use this dissecting device to cut an object into several pieces quickly and smoothly at a time.
