Facilitates cell transfer …from seeding to the bio-module Cell biologists familiar with conventional multi-well plates rapidly able to use ...the system Proprietary design/covered by three patents Quasi-VivoTM Cell Culture Systems Experimental design Basic - 2 chambers connected In series/parallel Complex – 32 chambers connected in series/parallel Quasi-VivoTM Cell Culture Systems PROVIDES IN-VIVO LIKE CONDITIONS FOR CELL GROWTH? VALIDATION I In primary hepatocytes xenobiotic gene expression is closer to in vivo. Cells maintain differentiation over a longer periods Cell morphology static Quasi-vivo Quasi-VivoTM Cell Culture Systems VALIDATION II - Correlation with drug metabolism/toxicity in vivo? Improved Sensitivity for Toxicity Screening: QuasiVivoTM EC50 Clinical Trial Result Conventional In vitro EC50 Diclofenac A non-steroidal antiinflammatory. Dose-response curve in Human Primary hepatocytes Quasi-VivoTM Cell Culture Systems Access to the Quasi-VivoTM system Quasi-VivoTM Cell Culture Systems ACCESS TO THE TECHNOLOGY Products: The Quasi-Vivo™ 100 Kit Bio-modules, reservoir bottle, connecting tubes, Peristaltic pump (Kit).
