Quasi-VivoTM Cell Culture Systems
Introduction to the Quasi-VivoTM system
Quasi-VivoTM Cell Culture Systems
INTER-CONNECTED CELL CULTURE …
Cells/tissue connected in series/parallel
Nutrient/media flow-through system
Allows cell-to-cell signalling
Metabolites/drugs/compounds circulate in system
Vitality/cell differentiation maintained
PROVIDES IN-VIVO LIKE (Quasi-vivo) CONDITIONS FOR CELL GROWTH
Quasi-VivoTM Cell Culture Systems
INTER-CONNECTED CELL CULTURE …
Quasi-VivoTM Cell Culture Systems
Chamber design
Minimises bubble formation
and shear stress
Shape & dimensions similar to
24 well plates. 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
