Abstract

We explore the utility of bioengineered human tissues-individually or connected into physiological units-for biological research. While much smaller and simpler than their native counterparts, these tissues are complex enough to approximate distinct tissue phenotypes: molecular, structural, and functional. Unlike organoids, which form spontaneously and recapitulate development, "organs-on-a-chip" are engineered to display some specific functions of whole organs. Looking back, we discuss the key developments of this emerging technology. Thinking forward, we focus on the challenges faced to fully establish, validate, and utilize the fidelity of these models for biological research.

  • Organs-on-chips are perfused microfluidic devices with engineered or miniaturized tissues linked by 3D microchannels to mimic organ functions, biomechanics and pathophysiological responses.

    “OoCs are perfused microfluidic platforms that contain bioengineered or miniaturized tissues or organs interconnected by 3D microchannels to simulate the in vivo functions, biomechanics and (patho)physiological responses of organs6,52–54.”

    From Human disease models in drug development (2023) · cites this paper as [53]

    The Introduction describes organs-on-chips as engineered tissue constructs that reproduce selected organ functions using physical signals and fabricated channels. But it says these constructs are not mini-organs, and the section on combining single-organ models describes several ways to connect them—not necessarily 3D microchannels. The claim therefore overstates what all organs-on-chips contain. Page numbers are unavailable in our copy. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
