Abstract

AIM: Head and neck squamous cell carcinomas (HNSCC) are solid tumors with low overall survival (40-60%). In a move toward personalized medicine, maintenance of tumor biopsies in microfluidic tissue culture devices is being developed. METHODOLOGY/RESULTS: HNSCC (n = 15) was dissected (5-10 mg) and either analyzed immediately or cultured in a microfluidic device (37°C) for 48 h. No difference was observed in morphology between pre- and postculture specimens. Dissociated samples were analyzed using trypan blue exclusion (viability), propidium iodide flow cytometry (death) and MTS assay (proliferation) with no significant difference observed highlighting tissue maintenance. Computational fluid dynamics showed laminar flow within the system. CONCLUSION: The microfluidic culture system successfully maintained HNSCC for 48 h, the culture system will allow testing of different treatment modalities with response monitoring.

(A) Laryngeal squamous cell carcinoma, staging T4aN0M0. (B) Transglottic laryngeal squamous cell carcinoma, staging T4N0M0. Each tumor is shown pre- and post-48-h microfluidic culture. The bright pink-stained areas on some of the images depict extracellular keratin (keratin pearls*), arising from the squamous cells. White arrows show infiltrating islands and cords of tumor cells. Tumor area showing orientation of cell maturation is circled in white. Pale stromal areas with inflammatory cells are circled in yellow. Intact basement membrane is shown by yellow arrows.

Figure 5. Computer simulation of fluid flow and velocity field in the microfluidic culture device. (A) Streamlines and velocity vectors of laminar fluid flow in the device. Labels show inlet, outlet and tissue sample location. (B) Velocity magnitude of the flow within the device. Color legend explains value of the velocity along the channel and the treatment chamber (m/s); thus, the maximum of the velocity equals 1.5 × 10-3 m/s or 1.5 mm/s.

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.
