High-Throughput Manipulation of Circulating Tumor Cells Using a Multiple Single-Cell Encapsulation System with a Digital Micromirror Device

Abstract

Circulating tumor cells (CTCs) are potential precursors of metastatic cancer, and genomic information obtained from CTCs have the potential to provide new insights into the biology of cancer metastasis. We previously developed a technique for single-cell manipulation based on the encapsulation of a single cell in a photopolymerized hydrogel that can be used for subsequent genetic analysis. However, this technique has limitations in terms of throughput because light irradiation must be performed on each individual cell from the confocal laser-scanning microscopy. Here, we present a high-throughput cell manipulation technique using a multiple single-cell encapsulation system with a digital micromirror device. This system enables rapid cell imaging within a microcavity array, a microfilter for the recovery of CTCs from blood samples, as well as the simultaneous encapsulation of several CTCs with hydrogels photopolymerized using a multiple light-irradiation system. Furthermore, single-cell labeling using two differently shaped hydrogels was examined to distinguish between NCI-H1975 cells and A549 cells, demonstrating the utility of the system for single-cell gene mutation analysis. In addition to CTCs, our system can be widely applied for analyses of mammalian cells and microorganisms.

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.
