  • Engineering individually addressable cellular spheroids using aqueous two-phase systems
    Patent number: 9874552
    Abstract: Provided are multi-phase systems that may be used to prepare a three-dimension aggregate of cells referred to as a cellular spheroid. The multi-phase system includes a droplet of an aqueous polymer phase within an immersion aqueous polymer phase. The droplet of the droplet aqueous polymer phase contains a three-dimensional aggregate of cells (cellular spheroid). Types of cells that may be used in the multi-phases system include stem cells and cancer cells. The cellular spheroids with the multi-phase system may be used to monitor cell growth in three-dimensional systems, or screen drugs in a three-dimension aggregate of cells.
    Type: Grant
    Filed: September 30, 2015
    Date of Patent: January 23, 2018
    Assignee: The University of Akron
    Inventors: Hossein Tavana, Ehsan Atefi, Stephanie Lemmo Ham
