Abstract

fetched live from OpenAlex

Clonal fitness and plasticity drive tumor heterogeneity contributing to disease progression and treatment resistance. Here, we provide a protocol to track the clonal outputs from uniquely marked cells. We describe steps for constructing and validating lentiviral DNA barcode libraries. We then detail procedures for single-cell RNA sequencing. This approach links clonal growth activity with transcriptomic profiles and enables permanent cellular labeling to track clonal dynamics in various model systems, which can provide insight into molecular processes underlying clone function. For complete details on the use and execution of this protocol, please refer to Nguyen et al. 1

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
