Tissue regeneration & repair

Tissue regeneration involves the restoration of tissue components by regrowth of damaged tissues. In contrast, tissue repair involves patching of injured tissue rather than restoring it. It is the proliferative capacity of the cells that decides the amount of regeneration against the repair that would occur in the tissue. Both regeneration and repair depending on the duration of the injury and response to the inflammation.
