This comparison does not assign a generated winner or score.
- Rodent (Rat) Transection
- Surgical blade cut through quadriceps belly
- 10 mcg/kg IM daily × 14 days
- 63% faster tendon-to-bone healing vs saline
- VEGF upregulation, Type I collagen density
- Gold standard for controlled injury staging. Consistent reproducibility across labs
- Rodent (Mouse) Eccentric Overload
- Forced lengthening contraction protocol
- 5 mcg/kg IM daily × 21 days
- 41% reduction in inflammatory markers at 7 days
- Fibroblast migration, MMP-2/MMP-9 regulation
- Mimics human strain mechanism but dose may be suboptimal. 10 mcg/kg standard in larger models
- Ex Vivo Tissue Culture
- Human quadriceps biopsy samples treated in vitro
- 1–10 mcg/mL peptide concentration in medium
- 2.7× collagen synthesis rate within 72 hours
- Direct fibroblast proliferation, integrin expression
- Demonstrates human cell response but lacks systemic factors (blood flow, immune modulation)
- Large Animal (Rabbit) Partial Tear
- Controlled laceration of rectus femoris
- 15 mcg/kg IM daily × 28 days
- 58% improvement in tensile strength at failure testing
- Angiogenesis density, Type I/Type III ratio
- Closest anatomical analog to human quad structure. Higher translational validity than rodent models
