Abstract
Since changes in mitochondrial morphology regulate key functions of stem cells, it is important to assess their structure under physiological and pathophysiological conditions. Here, we present techniques optimized in rare adult muscle stem cells (MuSCs). For evaluating mitochondrial length and volume within a compact cytoplasmic area in MuSCs on intact myofibers, we describe steps for mitochondrial staining, imaging, and quantification. For evaluating mitochondrial ultrastructure in small cell numbers, we describe steps for agarose embedding and quantification by TEM. For complete details on generation and use of this protocol, please refer to Baker et al. (2022).1

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
