A New Perspective on Revealing Tumor Heterogeneity through Single Cell RNA Sequencing
Bibliographic record
Abstract
This review paper mainly explores the application and prospects of single-cell RNA sequencing technology in the study of tumor heterogeneity. As an important concept in the field of oncology, tumor heterogeneity reveals the diversity and complexity of cells within a tumor, which has significant implications for tumor initiation, progression, treatment, and prognosis. However, traditional research methods have limitations in elucidating tumor heterogeneity. In recent years, the emergence of single-cell RNA sequencing technology has brought new breakthroughs to the study of tumor heterogeneity. This paper first introduces the concept and importance of tumor heterogeneity, then outlines the development and principles of single-cell RNA sequencing technology. Subsequently, it focuses on the specific applications of single-cell RNA sequencing in tumor heterogeneity research, including the identification of intra-tumoral cell subpopulations, the analysis of gene expression differences and regulatory networks, and the investigation of interactions among tumor cells. Finally, the contributions of single-cell RNA sequencing in tumor heterogeneity research are summarized, and future research directions are prospected.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
