Abstract
To develop specific conditional gene ablation in the hematopoietic myeloid-osteoclast lineage, transgenic mice expressing Cre recombinase under the control of the CD11b promotor were generated on the C57BL/6 background. The cellular specificity of Cre activity following recombination was quantified in the Z/EG reporter transgenic mice by FACS analysis with lineage-specific markers and EGFP coexpression. A high degree of recombination, as evidenced by EGFP-positive cells, was demonstrated in macrophages and granulocytes of bone marrow and spleen by the presence of double-positive cells CD11b/EGFP and Gr1/EGFP, respectively. Interestingly, the peritoneal macrophage population showed almost complete DNA recombination at large. Most important, mature osteoclast cells derived from the double transgenic bone marrow and spleen progenitors were EGFP-positive. Hence, these CD11b-Cre mice will provide a unique tool to unravel novel gene function and activities involved during osteoclast and macrophage differentiation and maturation processes.

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
