Abstract

Currently, there are no reliable ex vivo models that predict anticancer drug responses in human tumors accurately. A comprehensive method of mimicking a 3D microenvironment to study effects of anticancer drugs on specific cancer types is essential. Here, we report the development of a three-dimensional microfluidic cell array (3D μFCA), which reconstructs a 3D tumor microenvironment with cancer cells and microvascular endothelial cells. To mimic the in vivo spatial relationship between microvessels and nonendothelial cells embedded in extracellular matrix, three polydimethylsiloxane (PDMS) layers were built into this array. The multilayer property of the device enabled the imitation of the drug delivery in a microtissue array with simulated blood circulation. This 3D μFCA system may provide better predictions of drug responses and identification of a suitable treatment for a specific patient if biopsy samples are used. To the pharmaceutical industry, the scaling-up of our 3D μFCA system may offer a novel high throughput screening tool.

  • Current microfluidic tumor models with mimicked vasculature have demonstrated that tumor cells exhibit increased drug resistance when artificial blood vessels were used.

    “Current microfluidic tumor models with mimicked vasculature have demonstrated that tumor cells exhibit increased drug resistance when artificial blood vessels were used [81].”

    From Microfluidic modelling of the tumor microenvironment for anti-cancer drug development (2019) · cites this paper as [81]

    The Results (Profiles of Caspase-3 Activity in Different Culture Configurations; page unavailable) report slower and lower maximum drug responses in PC9 lung cancer cells cultured with mimicked microvessels than in static 3D coculture. This supports reduced drug response in that comparison, but the broader claim of increased tumor-cell drug resistance overstates the finding: the authors measured apoptotic response and only speculate that the endothelial layer delayed drug delivery. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • In a device with an HMVEC monolayer on a porous PDMS layer, human non-small cell lung cancer PC9 cells had stronger drug resistance to four different apoptotic inducers than two-dimensional cultured PC9 cells.

    “It was shown that human non-small cell lung cancer cells (PC9) cultured in their devices had stronger drug resistance to four different apoptotic inducers than two-dimensional cultured PC9 cells.”

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.
