Episode notes
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.
Chronic Inflammation Drives Fibrosis
- Chronic inflammation diverts regenerative signals toward fibroblast activation and fibrosis.
- Repeated toxin exposure (e.g., alcohol) leads to cirrhosis by persistent fibroblast-driven scarring.
