A microfluidic based experimental methodology has been developed that offers a biomimetic microenvironment in which pseudo in vivo tissue studies can be carried out under in vitro conditions. Using this innovative technique, which utilizes the inherent advantages of microfluidic technology, liver tissue has been kept in a viable and functional state for over 70 h during which time on-chip cell lysis has been repeatedly performed. Tissue samples were also disaggregated in situ on-chip into individual primary cells, using a collagenase digestion procedure, enabling further cell analysis to be carried out off-line. It is anticipated that this methodology will have a wide impact on biological and clinical research in fields such as cancer prognosis and treatment, drug development and toxicity, as well as enabling better fundamental research into tissue/cell processes.
