Zebrafish Danio rerio myotomal muscle structure and growth from a spatial transcriptomics perspective
Bibliographic record
Abstract
Fish exhibit different muscle structures and growth characteristics compared with mammals. We used a spatial transcriptomics approach and examined myotomal muscle sections from zebrafish. Adult muscles were divided into eight regions according to spatial gene expression characteristics. Slow muscle was located in the wedge-shaped region near the lateral line and at the base of the dorsal fin, intermediate muscle was located in a ribbon-shaped region adjacent to slow muscle, and fast muscle was located in the deep region of the trunk, surrounded by intermediate muscle; the interior of fast muscle was further divided into 6 parts by their transcriptomic features. Combined analysis of adult and larval data revealed that adult muscles contain specific regions similar to larval muscles. These regions showed active myogenesis and a high expression of genes associated with muscle hyperplasia. This is the first study to apply spatial transcriptomics to fish myotomal muscle structure and growth.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
