Veit Bergendahl 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).

  • Automated method and apparatus for embryonic stem cell culture
    Patent number: 8815585
    Abstract: The invention concerns methods for automated culture of embryonic stem cells (ESCs) such as human ESCs. In some aspects, methods of the invention employ optimized culture media and limited proteolytic treatment of cells to separate cell clusters for expansion. Automated systems for passage and expansion of ESCs are also provided.
    Type: Grant
    Filed: June 30, 2008
    Date of Patent: August 26, 2014
    Assignee: Cellular Dynamics International, Inc.
    Inventors: Nathaniel Beardsley, Veit Bergendahl, Megan Fitzgerald, Christine Daigh

  • Clonal culture of human pluripotent stem cells
    Patent number: 7892830
    Abstract: While culture medium and systems have been described that permit the culture and proliferation of human embryonic stem cells in feeder free and animal product free conditions, these conditions will not readily support cloning of an embryonic stem cell culture meaning, at least here, the initiation of a sub-culture using one or a very few originating cells. It has been found here that a class of small molecules that are inhibitors of kinase enzymes will increase the efficiency of cloning of stem cell cultures sufficiently to make such cloning practical in the defined medium and in other media as well.
