Abstract

A novel three-dimensional cell culture system was constructed with an array of cell panels (4 x 5) in a silicon chip, together with multi-channel drug containers. Human breast cancer (MCF-7) cells were embedded in a collagen-gel matrix and entrapped in a pyramidal-shaped silicon hole. Each cell panel can be isolated by a channel composed of a microfluid part and a reservoir. A cell panel was exposed to 200 mm KCN for 2 days to demonstrate that each cell panel could be independently evaluated under various stimulation conditions. Based on the cellular respiration activity, the proliferation behavior was continuously monitored on the silicon-based cell array for 5 days using scanning electrochemical microscopy (SECM). The cells entrapped in the device (3-D culture) proliferated normally, and the proliferation rate was lower than that of cells grown in a monolayer cell culture (2-D culture). The effects of three anticancer drugs measured simultaneously on the cell chip were in good agreement with those obtained by a conventional colorimetric assay. Our results suggest that the silicon-based device for 3D culture is appropriate for a chemosensitivity assay involving multi-chemical stimulation.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Other researchers have used 3D cell-based electrochemical biosensors to quantify cancer cell resistance to drug compounds and to study cancer cell proliferation in the presence of anticancer drugs.

    “Other researchers have used 3D cell-based electrochemical biosensors to quantify cancer cell resistance to drug compounds 78,95 and to study cancer cell proliferation in the presence of anticancer drugs. 94”
  • Anticancer drug screening has been an important application for 3D cell culture biosensors because biosensor-based assays enable multiplex analysis of different drugs and/or cancer 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.
