The Cell Cycle and Cell Fate in Tissue Regeneration and Healing
The cell cycle and cell fate explain how tissue grows back after injury, and why some tissues regenerate fast while others never do. A cell can only do three things: divide (proliferate), specialize (differentiate), or die by apoptosis. Regeneration replaces lost cells, healing undoes the damage from necrosis or inflammation, and how quickly a tissue regenerates depends on how fast its cells normally turn over.
