Vascularized cancer on a chip: The effect of perfusion on growth and drug delivery of tumor spheroid
Open accessAbstract
Tumor vasculature creates a hostile tumor microenvironment (TME) in vivo and nourishes cancers, resulting in cancer progression and drug resistance. To mimic the biochemical and biomechanical environments of tumors in vitro, several models integrated with a vascular network have been reported. However, the tumor responses to biochemical and biomechanical stimuli were evaluated under static conditions and failed to incorporate the effects of blood flow to tumors. In this study, we present a tumor-on-a-chip platform that enables the evaluation of tumor activities with intraluminal flow in an engineered tumor vascular network. The fibroblasts in the tumor spheroid induced angiogenic sprouts, which constructed a perfusable vascular network in a tumor spheroid. The perfusability of the engineered vascular network was preserved during the culture. Moreover, perfusion for over 24 h significantly increased the proliferation activities of tumor cells and decreased cell death in the spheroid. Drug administration under perfusion condition did not show the dose-dependent effects of anticancer drugs on tumor activities in contrast to the results under static conditions. Our results demonstrate the importance of flow in a vascular network for the evaluation of tumor activities in a drug screening platform.

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.
