tissue regeneration
Cells replacing themselves
Tissue regeneration is the biological process by which organisms repair or replace damaged cells, tissues, or organs.
Some creatures regenerate dramatically—salamanders regrow limbs, starfish regenerate from fragments.
In humans, the liver regenerates readily while nerve tissue does so poorly.
Medical research pursues ways to enhance regeneration: stem cell therapy for tissue regeneration, tissue regeneration after a heart attack.
