  • Patent number: 11554138
    Abstract: The present disclosure relates to methods of using cisplatin active agents in which reduced organ toxicity is observed are provided. In the subject methods, an effective amount is administrated to the host before administration of an effective amount of cisplatin active agents. The cisplatin toxicity reducing agent comprising of stable bismuth(III) complexes or pharmaceutically acceptable salts reduces the levels of undesired toxicity of cisplatin active agents without compromising their anticancer activity. Also provided are methods for use in practicing the subject methods in the treatment of different disease conditions.
    Type: Grant
    Filed: July 14, 2016
    Date of Patent: January 17, 2023
    Assignee: THE UNIVERSITY OF HONG KONG

  • Publication number: 20080031858
    Abstract: A method has been developed to produce stable cell-matrix microspheres with up to 100% encapsulation efficiency and high cell viability, using matrix or biomaterial systems with poor shape and mechanical stability for applications including cell therapeutics via microinjection or surgical implantation, 3D culture for in vitro expansion without repeated cell splitting using enzymatic digestion or mechanical dissociation and for enhanced production of therapeutic biomolecules, and in vitro modeling for morphogenesis studies. The modified droplet generation method is simple and scalable and enables the production of cell-matrix microspheres when the matrix or biomaterial system used has low concentration, with slow phase transition, with poor shape and mechanical stability.

  • Publication number: 20070292514
    Abstract: A bioengineered IVD for disc replacement has been developed that has mechanical and structural support characteristics similar to those of native IVD. Extracellular matrix (ECM) provides support to living cell components and interacts with the living cellular components during the fabrication process without introducing toxicity. The composition can be produced from both natural or synthetic source but preferably natural and induced to self-assemble or reconstitute into its solid form under conditions that are mild enough to support cellular survival and growth. The cells induce a volume change of the structures, leading to changes in dimension, ECM density, cell density mechanical property and stability, etc. The extent of the change i volume of the composition can be precisely controlled by factors such as the density of the ECM, the density of the living cells, the timing for interaction and the serum concentration. Increased structural support is provided by crosslinking.
