Abstract
Successful gene therapy for most inherited diseases will require stable expression of the therapeutic gene. This can be addressed with integrating or self-replicating viruses by targeting postmitotic cells that have a long lifetime or stem cells that can replenish defective tissue with corrected cells. In this study, we explore the possibility of targeting a muscle stem cell population in situ through in vivo administration of vector. To develop this concept, we selected a mouse model of muscular dystrophy (mdx mice) that undergoes rapid turnover of muscle fibers. In vivo targeting of muscle progenitor cells, notably satellite cells, with a pseudotyped lentiviral vector encoding the minidystrophin restores dystrophin expression and provides functional correction in skeletal muscle of mdx mice. This study shows that progenitor cells can be genetically engineered in vivo and subsequently proliferate into terminally differentiated tissue carrying the genetic graft in a way that stably corrects function.

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
