  • Methods to enhance cell migration and engraftment
    Patent number: 9096831
    Abstract: A method is provided to functionally select cells with enhanced characteristics relevant to cell engraftment, including both spontaneous migration and directional migration towards specific chemo-attractants. The cells are preferably undifferentiated cells, such as mesenchymal stem cells. The method involves entrapping or encapsulating the cells in a biomaterial barrier, optionally inducing cell migration, and selecting cells that migrated through the barrier. The cells selected by this method have better migratory activities and enhanced in vivo engraftment to injured tissues when they are supplemented systemically.
    Type: Grant
    Filed: June 14, 2011
    Date of Patent: August 4, 2015
    Assignee: Versitech Limited
    Inventors: Barbara Pui Chan, Hoi Ling Wong, Mei Yi Wong, Godfrey Chi-Fung Chan, Zhen Fan Yang

  • Anti-cancer phosphine containing [Au(CNC)L] complexes and derivatives thereof and methods for treating cancer using such compositions
    Patent number: 7632827
    Abstract: Gold(III) phosphine complexes [Aum(CNC)mL]n+ (where HCNCH=2,6-diphenylpyridine) and their use as anti-tumor agents are disclosed. Notable results for the appearance of new potential anti-tumor application of these gold(III) complexes are reported. The described complexes show promising cytotoxic properties toward cancer cells in both in vitro and in vivo studies.
