Regeneration and Repair by Connective Tissue
After destruction, cells and tissues can be replaced by vital cells through parenchymal regeneration or by connective tissue repair.
Repair by connective tissue starts with formation of granulation tissue. It may appear in chronic peptic ulcer, surrounding necrotic areas (infarct, inflammation) or fibrin (fibrinous inflammation, thrombus). With time, the maturation of granulation tissue will replace the damaged area with a scar.
