Repair
Overview: The process of repair begins very early. Repair involves regeneration of the parenchyma or replacement of damaged tissue with a scar if regeneration is not possible.
Definitions: Healing versus regeneration
Regeneration is complete replacement of damaged cells, with no scar formation.
- Can occur in renewing tissues (e.g., gastrointestinal tract and skin).
- Can occur in stable tissues (e.g., compensatory growth in the liver).
Healing is regeneration of cells combined with scarring and fibrosis.
