Standardizing designed and emergent quantitative features in microphysiological systems

Article / Letter to editor
Microphysiological systems (MPSs) are cellular models that replicate aspects of organ and tissue functions in vitro. In contrast with conventional cell cultures, MPSs often provide physiological mechanical cues to cells, include fuid fow and can be interlinked (hence, they are often referred to as microfuidic tissue chips or organs-on-chips). Here, by means of examples of MPSs of the vascular system, intestine, brain and heart, we advocate for the development of standards that allow for comparisons of quantitative physiological features in MPSs and humans. Such standards should ensure that the in vivo relevance and predictive value of MPSs can be properly assessed as ft-for-purpose in specifc applications, such as the assessment of drug toxicity, the identifcation of therapeutics or the understanding of human physiology or disease. Specifcally, we distinguish designed features, which can be controlled via the design of the MPS, from emergent features, which describe cellular...Show moreMicrophysiological systems (MPSs) are cellular models that replicate aspects of organ and tissue functions in vitro.

Specifcally, we distinguish designed features, which can be controlled via the design of the MPS, from emergent features, which describe cellular function, and propose methods for improving MPSs with readouts and sensors for the quantitative monitoring of complex physiology towards enabling wider end-user adoption and regulatory acceptance.
