This presentation summarizes the current knowledge on the kinetics of stratified epithelia
Properties of stratified epithelia
1. Their unit is called  :Epithelial Proliferative Unit  (EPU)
2. EPU is monoclonal
3. EPU is oriented from stem cell and outward
4. Cells stream outward (to their graveyard)
5. As cells stream they differentiate.
6. Cells do not stream inward, they do not de-differentiate.
