Kirkstall’s Quasi Vivo^® system provides many benefits that will contribute to the development of better (more predictive) models:

• Human cells, whether healthy or diseased, can be cultured for long periods (more than 28 days), allowing the development of the disease or the effect of repeated dose therapies to be studied.
• Complex pathways and interactions in co-culture of different cell types can be studied using the interconnected chambers that form the building blocks of Quasi Vivo^®.
• Tissue slices, individual cells seeded on a scaffold or 2D simple culture on a cover slip can be used in easy-to-handle systems that deliver media in single pass or recirculating systems.
• Media perfusion has been demonstrated to improve cell viability, proliferation and function, even for difficult to culture cells such as human primary hepatocytes.

Supply of healthy human cells has always been problematic. Quasi Vivo^® will work well with primary human cells from donor tissues, differentiated stem cells, tissue slices or even animal cells or cell lines, even though the latter are now recognised as being of limited value as a predictive tool for human responses.

Quasi-Vivo^® is currently being used in a wide variety of disease and organ models including liver, kidney, cardiovascular, brain and respiratory epithelium.
