Abstract
This study concerns the cytogenetic stability of in vitro human bone marrow-derived mesenchymal stem cells (MSCs) in primary culture and after passaging. Bone marrow samples were collected from seven brain malfunction patients involved in autologous MSC transplantation trials. Chromosome preparations from primary MSC cultures and after 3 passages were analyzed by conventional staining and G-banding techniques. All MSCs showed normal diploid karyotypes, 46 XY or 46 XX, without aneuploidy or polyploidy; chromosome structural abnormalities were not detected. The results indicate that the in vitro cultured MSCs retained normal cytogenetics before being transplanted back into the patients.

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
