A Mechanistic Model of Platelet-Rich Plasma Treatment for Androgenetic Alopecia
Bibliographic record
Abstract
BACKGROUND: Platelet-rich plasma (PRP) therapy is a novel procedure used to treat androgenetic alopecia (AGA). OBJECTIVE: Propose a mechanism of action of PRP therapy for AGA. METHODS AND MATERIALS: A thorough literature search including PRP research for AGA therapy as well as PRP research in other areas of medicine was conducted. RESULTS: A mechanistic model for the action of PRP on the hair follicle was created. CONCLUSION: Platelet-rich plasma therapy stimulates hair growth through the promotion of vascularization and angiogenesis, as well as encourages hair follicles to enter and extend the duration of the anagen phase of the growth cycle. The process is accomplished through growth factor-mediated increased activation of wingless (Wnt)/β-catenin, extracellular signaling regulated kinase (ERK), and protein kinase B (Akt) signaling pathways, which leads to the necessary cellular proliferation and differentiation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
