Abstract
Understanding how bone marrow-derived cells (BMDCs) enter the central nervous system (CNS) is critical for the development of therapies for brain-related disorders using hematopoietic stem cells. We investigated the brain damages and blood-brain barrier (BBB) modification following either whole-body irradiation or a myeloablative chemotherapy regimen in mice, and the capacity for these treatments to induce the entry of BMDCs into the CNS. Neither treatment had a lasting effect on brain integrity and both were equally efficient at achieving myeloablation. Injection of bone marrow cells from green fluorescent protein (GFP) transgenic mice was able to completely repopulate the hematopoietic niche in the circulation and in hematopoietic organs (thymus and spleen). However, GFP(+) cells only entered the brain following whole-body irradiation. We conclude that myeloablation, damages to the brain integrity, or the BBB and peripheral chimerism are not responsible for the entry of BMDCs into the CNS following irradiation.

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
