Episode notes
Four Stages Underpin Wound Repair
- Wound healing follows four overlapping stages: hemostasis, inflammation, proliferation, and remodeling.
- Each stage both solves an immediate problem and signals the next stage via chemical mediators.
Tissue Classes Predict Healing Ability
- Tissues classify as labile, stable, or permanent based on regenerative capacity.
- Labile tissues (skin, GI epithelium) regenerate best; permanent tissues (neurons, myocardium) form scars.
Regeneration Versus Scar Is Tissue-Dependent
- Tissue repair follows two outcomes: true regeneration or scar formation.
- Regeneration depends on tissue type and remaining stem-cell capacity.
