Detailed explanation-1: -Tissue regeneration is a complex cellular process that involves an interplay of growth factors (GFs), genes, chemokines, cytokines, and other signaling molecules.
Detailed explanation-2: -Regeneration involves restitution of tissue components; repair involves “patching” rather than restoring. The amount of regeneration vs. repair that occurs depends on the proliferative capacity of the cells, the integrity of the stromal framework and the duration of the injury and inflammatory response.
Detailed explanation-3: -Tissue regeneration includes regeneration of epithelial tissue, regeneration of fibrous tissue, regeneration of cartilage tissue and bone tissue, regeneration of blood vessels, regeneration of muscle tissue, and regeneration of nerve tissue.
