In Vitro Clonal Culture of Human Hematopoietic Progenitor Cells
Bibliographic record
Abstract
Human hematopoietic tissue represents a complex developmental system that is closely regulated to ensure the maintenance of appropriate levels of circulating blood cells. At least nine distinct lineages of cells at various stages of maturation have been described (1). Substantial progress in the study of hematopoietic stem cell ontogeny has resulted from the development of semisolid culture methods for the detection of committed progenitor cells. The assays define specific individual precursor cells indirectly by the ability of these cells to form colonies consisting of clonally expanded progeny at varying stages of differentiation. In turn, these methods have led to the identification, characterization, and synthesis by recombinant DNA techniques of some of the growth factors capable of stimulating colony formation and infer to an in vivo regulatory role for such factors in hematopoiesis.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
