Abstract
Studies on cellular heterogeneity have emerged as a powerful approach for developing new strategies to treat diseases including cancer. However, it is difficult to set up an in vitro co-culture experiment to study the interaction of individual live cells. In this paper, we report a hydrodynamic shuttling chip (HSC) which can deterministically capture single cells into microfluidic chambers to set up multiple single-cell co-culture experiments in which individual live cells can be microscopically observed. Using this chip device, we demonstrated a triple single-cell culture of oral squamous cell carcinoma and lymphatic endothelial cells to observe the effect of cell-cell interaction on the cell motility. Triple, single-cell pairing efficiency by our HSC device was eightfold higher than that of the probabilistic method. Using this HSC device, we were able to perform triple-culture experiments to show the cell type-dependent motility of oral squamous cell carcinoma and lymphatic endothelial cells, which was not observed in co-culture experiments.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
